typesafe-units

unit converter with focus on type-safety, simplicity and performance.

Key Features

Converting

const converted = units.from(3, "cm").to("in");
console.log(converted);
// Output: 1.1811

Comparing

const c1 = units.Convertible(100, "kilometer");
const c2 = units.Convertible(1000, "meter");

if (c1.lt(c2)) {
    console.log(`${c1} is less than ${c2}!`);
} else if (c1.eq(c2)) {
    console.log(`${c1} and ${c2} are equal!`);
} else {
    console.log(`${c1} is greater than ${c2}!`);
}
// Output: 100km is greater than 1000m!

Formatting

const convertible = units.Convertible(12.2323123, "kt");
console.log(convertible.format("%.2f %s", { length: "long" }));
// Output: 12.23 knots
