v0.4.0 — data transfer rate, acceleration & illumination (20 categories)

v0.4.0 — three new categories: data transfer rate, acceleration, illumination (now 20 total)

New / 新增:

• data transfer rate — tbit/s…bit/s (decimal bits), tb/s…b/s (decimal bytes), tib/s…kib/s (binary bytes). The classic mix-up answered exactly: 100 Mbps = 12.5 MB/s. mb/s = megabyte/s (data-table rule), mbps/mbit/s = megabit/s.
• acceleration — m/s2, g0 (standard gravity 9.80665 m/s²), ft/s2, mph/s. 1 g = 32.174049 ft/s², 60 mph/s = 26.8224 m/s². g stays the gram — gravity is g0 / gravity / g-force.
• illumination — klx, lx (lux), fc (foot-candle, 1 fc = 10.76391 lx), ph (phot).
• The old data size / transfer category is now data size (sizes only); rates live in data transfer rate.

Still zero runtime dependencies, pure arithmetic, all outputs anchored to an independent Python oracle. 49 tests green, coverage 93.65%.

中文：v0.4.0 新增三个类别——数据传输速率（100 Mbps = 12.5 MB/s 精确换算；mb/s 为兆字节、mbps/mbit/s 为兆比特）、加速度（标准重力 g0、g-force、ft/s2、mph/s）、照度（lux/klx/英尺烛光 fc/辐透 ph）；原「数据大小/传输」类别更名为「数据大小」。共 20 个类别，零运行时依赖不变，锚点全部由独立 Python oracle 定值。

v0.3.0 — power, force & torque

v0.3.0 — power, force & torque (the mechanics trio)

Three new categories, still zero runtime dependencies and pure arithmetic — 17 categories in total.

What's new

• power — mw, kw, w, hp (mechanical = 550 ft·lbf/s), hp(m) (metric PS), hp(e) (electric 746 W), btu/h (IT), ftlb/s. The three different horsepower definitions are kept strictly separate — a classic LLM error point.
• force — kn, n, dyn, lbf, kgf (kp), gf. lbf/kgf are weight-based forces at standard gravity 9.80665 m/s².
• torque — n.m, kgf.m, lbfft (pound-force foot), lbfin (pound-force inch). Force × length.

Symbol disambiguation

• typed kn resolves to knot (speed); use the full name kilonewton for kN.
• nm is the nanometer (length); the torque newton meter uses the symbol n.m (also n·m or full names).

Examples

convert_unit { value: 150, from: "kw", to: "hp" }    → 150 kw = 201.153313 hp
convert_unit { value: 1, from: "lbf", to: "n" }      → 1 lbf = 4.448222 n
convert_unit { value: 1, from: "lbfft", to: "n.m" }  → 1 lbfft = 1.355818 n.m

Install

41 tests green (independent closed-form anchors), oxlint clean, forbidden-word scan clean, install self-test passed.

v0.3.0 — 功率、力、扭矩（力学三件套）

新增 3 个类别，依旧零运行时依赖、纯算术——共 17 个类别。

• 功率：mw/kw/w/hp（机械马力 = 550 ft·lbf/s）/hp(m)（公制 PS）/hp(e)（电动 746 W）/btu/h/ftlb/s——三种马力定义严格区分，正是大模型高频出错点。
• 力：kn/n/dyn/lbf/kgf/gf——lbf/kgf 按标准重力 9.80665 m/s² 计算。
• 扭矩：n.m/kgf.m/lbfft/lbfin——力×长度。

符号消歧：输入 kn 解析为"节"（速度），千牛请用全名 kilonewton；nm 是纳米（长度），扭矩牛米用 n.m（也支持 n·m 或全名）。

安装：dsh plugin --profile default add github:TYEclipse/dsh-units

41 个测试全绿（独立闭式锚点）、oxlint 零告警、违禁词扫描干净、安装自测通过。
