Safe Units

code:ts

import { bars, kilograms, Measure, meters, milli, seconds } from "safe-units";

const width = Measure.of(3, meters);

const height = Measure.of(4, meters);

const area = width.times(height).scale(0.5);

const hypot = Measure.sqrt(width.squared().plus(height.squared())); // 5 m

const mass = Measure.of(30, kilograms);

const mps2 = meters.per(seconds.squared());

const acceleration = Measure.of(9.8, mps2);

const force = mass.times(acceleration); // 294 N

const pressure = force.over(area); // 49 Pa

const maxPressure = Measure.of(0.5, milli(bars)); // 0.5 mbar

pressure.lt(maxPressure) // true

method chain styleかぁ〜

ちょっときつそう
