Conversion ​

Every converter has the same shape:

ts
interface UnitConverter {
	(amount: number): number;
	from: (ms: number) => number;
}
  • Calling it converts an amount of the unit to milliseconds.
  • .from(ms) converts milliseconds to an amount of the unit.

See Converting units for examples.

weeks ​

ts
weeks(amount: number): number
weeks.from(ms: number): number

Converts weeks to milliseconds, and .from() converts milliseconds to weeks. One week is 604_800_000 milliseconds.

days ​

ts
days(amount: number): number
days.from(ms: number): number

Converts days to milliseconds, and .from() converts milliseconds to days. One day is 86_400_000 milliseconds.

hours ​

ts
hours(amount: number): number
hours.from(ms: number): number

Converts hours to milliseconds, and .from() converts milliseconds to hours. One hour is 3_600_000 milliseconds.

minutes ​

ts
minutes(amount: number): number
minutes.from(ms: number): number

Converts minutes to milliseconds, and .from() converts milliseconds to minutes. One minute is 60_000 milliseconds.

seconds ​

ts
seconds(amount: number): number
seconds.from(ms: number): number

Converts seconds to milliseconds, and .from() converts milliseconds to seconds. One second is 1_000 milliseconds.

milliseconds ​

ts
milliseconds(amount: number): number
milliseconds.from(ms: number): number

Returns its input unchanged, in both directions. It exists so every unit works the same way; see the FAQ.

microseconds ​

ts
microseconds(amount: number): number
microseconds.from(ms: number): number

Converts microseconds to milliseconds, and .from() converts milliseconds to microseconds. One microsecond is 0.001 milliseconds.

nanoseconds ​

ts
nanoseconds(amount: number): number
nanoseconds.from(ms: number): number

Converts nanoseconds to milliseconds, and .from() converts milliseconds to nanoseconds. One nanosecond is 0.000_001 milliseconds.
