dsh-unitverse · Unit Converter

English | 中文 · Changelog

The name reads unit + universe: ten categories of units in one universe. The GUI view tab is still called 单位换算 / Unit Converter, and the model-facing tool is still convert.

A DeepSeek Harness (DSH) unit conversion plugin exposing one convert tool across length, area, volume, time, angle, speed, temperature, pressure, energy/heat and power, with case-insensitive English and Chinese unit names, plus both absolute-temperature and temperature-difference (Δ) modes.

Preview

English UI — one independent module per category, listing only that category's units:

Unit Converter view (English UI)

Chinese UI — all copy, category names and unit names in Chinese:

单位换算视图（中文界面）

Features

✅ 10 categories, 80+ common units (metric, imperial/US customary, common Chinese units)
✅ Lenient unit spelling: km / KM / kilometer / 千米 / 公里 all resolve
✅ Absolute temperature (°C / °F / K / °R) and temperature difference (Δ°C ↔ Δ°F)
✅ Pure TypeScript, zero runtime dependencies, side-effect free and unit-testable
✅ Results rounded to ~10 significant digits by default
✅ Clear errors for unknown units or cross-category requests
✅ Web UI view: a "Unit Converter" tab next to Conversation / Trajectory in the session view bar; the panel is split into ten independent category modules (units are never mixed), and all copy — unit names included — follows the DSH zh/en UI language (since v0.1.0, requires the DSH Web GUI, 0.1.0-rc.6+)

Supported categories and units

Category	Base	Units (symbols)
length	m	nm, μm, mm, cm, m, km, in, ft, yd, mi, nmi, 里 (li), 尺 (chi)
area	m²	mm², cm², m², km², ha, 亩 (mu), in², ft², yd², acre, mi²
volume	m³	mL, L, m³, cm³, in³, ft³, yd³, gal (US), gal (UK), qt (US), bbl
time	s	ms, s, min, h, d, wk, mo, yr
angle	rad	rad, ° (deg), grad, ′ (arcmin), ″ (arcsec), turn
speed	m/s	m/s, km/h, mph, kn (knot), ft/s
temperature	K	°C, °F, K, °R (Δ prefix available for differences)
pressure	Pa	Pa, kPa, MPa, hPa, bar, atm, psi, Torr, mmHg, inHg
energy	J	J, kJ, MJ, cal, kcal, Wh, kWh, BTU
power	W	W, kW, MW, GW, hp, PS

Every unit also accepts its English full name (including plurals) and its Chinese name as aliases — e.g. ft, foot, feet and 英尺 are the same unit.

Installation

Install it as a DSH bundle — published on npm as dsh-unitverse; a local checkout, a tarball or GitHub work too:

# From npm (recommended)
dsh plugin --profile <profile-name> add dsh-unitverse

# From a local checkout
dsh plugin --profile <profile-name> add ./dsh-unitverse

# Or from GitHub (build artifacts are committed, so no allowBuilds needed)
dsh plugin --profile <profile-name> add github:runcat-tommy/dsh-unitverse

package.json declares dsh.bundle, so dsh plugin add registers the plugin row from cordis.patch.yml automatically.

The package also ships a browser half: the dsh.client declaration plus lib/client.js behind the exports["./client"] entry. Installed into a profile that runs the Web GUI, a "Unit Converter" tab appears in the session view bar (see Web converter view below). In CLI-only profiles the client part is simply never loaded and the tool keeps working.

Web converter view (v0.1.0+)

After installing and restarting the DSH GUI process (dsh web etc.), open any session: the view tab bar now shows "Unit Converter" next to Conversation / Trajectory (the Chinese UI shows 单位换算):

One module per category: the panel opens with ten category tabs — Length, Area, Volume, Time, Angle, Speed, Temperature, Pressure, Heat / Energy and Power. Switching a tab switches the module, and a module only ever lists its own units, so units from different categories are never mixed and a cross-category conversion cannot be produced. Each module starts from a common unit pair (e.g. Length → km ↔ mi).
Unit dropdowns: source and target units are picked from a list showing symbol · name — no unit name has to be typed, so nothing can be misspelled.
Instant result: typing a value updates the result immediately, shown as a large number + unit, the full equation and a category badge, with one-click copy.
One-click ⇄ swap of source and target.
The Temperature module adds a Difference Δ switch: off converts absolute scales (°C → °F), on converts intervals (Δ°C → Δ°F), with an explanatory hint.
Recent conversions are kept per category (browser localStorage); click any row to restore it, or clear the current category’s rows in one click.
Fully follows the DSH UI language: in a Chinese environment every string — including unit names such as 千米 / 摄氏度 — is Chinese; in an English environment everything is English ("kilometer", "degree Celsius"), category names and tabs included. Switching the language refreshes the panel and the history immediately.
The view is pure front-end: the conversion core is bundled into lib/client.js, so conversions run locally in the browser — no model or server round-trip involved.

Usage

Once installed, the model can call the convert tool:

convert(value=100, from="km", to="mi")   -> 62.13711922 mi

Tool parameters:

Parameter	Type	Required	Description
`value`	number	yes	The numeric amount (finite number)
`from`	string	yes	Source unit: symbol / English / Chinese, case-insensitive
`to`	string	yes	Target unit: symbol / English / Chinese, case-insensitive

Returns a structured result: { value, from, to, result, category, categoryZh, categoryEn, fromInput, toInput, summary } (fromInput / toInput are the caller's original tokens; from / to are the resolved canonical names).

Examples

"Convert 100 km to miles"
→ convert(100, "km", "mi") → summary: "100 km = 62.13711922 mi (length)"

"How many cm is 5 feet?"
→ convert(5, "feet", "cm") → summary: "5 feet = 152.4 cm (length)"

"36 km/h to m/s"     → convert(36, "km/h", "m/s")     → 10
"1 atm to kPa"       → convert(1, "atm", "kPa")       → 101.325
"212 °F to °C"       → convert(212, "°F", "°C")       → 100

Temperature differences (Δ)

Temperature converts as an absolute scale by default. For a temperature difference, prefix BOTH units with Δ or delta:

"What is a 1 °C temperature interval in °F?"
→ convert(1, "Δ°C", "Δ°F") → 1.8

Mixing an absolute and a Δ unit (e.g. Δ°C → K) is rejected to avoid ambiguous "degrees Kelvin"-style semantics; the error names both repairs (add Δ to both, or drop it from both). Delta results keep the Δ marker in the echoed units, so an interval is never mistaken for an absolute reading:

convert(10, "Δ°C", "Δ°F") → summary: "10 Δ°C = 18 Δ°F (温度)"
convert(10, "°C", "°F")   → summary: "10 °C = 50 °F (温度)"   ← absolute, a different result

Precision and conventions

Results round to ~10 significant digits by default; the core convert() accepts a significantDigits option (1–15).
cal is the thermochemical calorie (1 cal = 4.184 J); use kcal / 大卡 for the food "Calorie".
BTU is the International Table BTU (1 BTU = 1055.05585262 J).
yr (year) is the Julian year of 365.25 days; mo (month) = year / 12.
The Chinese character 度 means degrees (angle); write 千瓦时 for kWh (avoid ambiguity with 度).
Chinese 分/秒 in a time context map to min/s; use arcmin/arcsec (角分/角秒) for angular minutes/seconds.

Using the core library directly

The conversion core is a zero-dependency pure module:

import { convert, convertDetailed } from 'dsh-unitverse'

convert(100, 'km', 'mi')                 // 62.13711922
convert(25, '°C', '°F')                  // 77
convert(1, 'Δ°C', 'Δ°F')                 // 1.8 (temperature difference)
convertDetailed(3, 'km/h', 'm/s')        // { result: 0.833..., summary: '...' }

src/index.ts is the DSH plugin entry (depends on @deepseek-ai/cordis and @deepseek-ai/dsh-tools); src/convert.ts + src/units.ts form the host-independent core library.

Development

npm install
npm test          # full vitest suite (conversions, aliases, temperature, edges,
                  # plugin registration, lib/client.js smoke tests)
npm run typecheck # tsc --noEmit
npm run build     # tsup -> lib/ (ESM + CJS + d.ts), then scripts/build-client.mjs
                  # emits lib/client.js (the ModuleLoader lazy-CJS bundle)

Repository layout

src/units.ts             unit tables and alias index (single source of truth)
src/convert.ts           conversion engine: parsing, converting, temperature/Δ, precision, errors
src/index.ts             DSH plugin entry (server/CLI side): registers the convert tool
src/client/              Web client plugin (browser side):
                           index.tsx          registers the conversation.view entry
                           UnitConvertView.tsx  converter panel (pure front-end core)
                           locales.ts         zh/en UI copy
scripts/build-client.mjs esbuild wrapper that emits lib/client.js (ModuleLoader lazy-CJS format)
test/                    Vitest tests (incl. lib/client.js smoke tests)
cordis.patch.yml         DSH bundle patch layer
lib/                     build output (committed so GitHub installs need no build)

src/convert.ts + src/units.ts form the host-independent core library: the server tool imports it, and the same code is bundled into the browser-side lib/client.js, so conversions in the Web view happen entirely locally.
