⏱️ Time Converter

Convert between seconds, minutes, hours, days, weeks, months and years. Month and year conversions use calendar averages (1 year = 365.2425 days in the Gregorian calendar).

From

1 ns = 0.001 µs

Precision

1 nanoseconds = 0.001 microseconds

1 × 0.001 = 0.001

1 ns equals 0.001 µs, so multiplying by 0.001 converts the value. The result describes the exact same quantity — only the measuring stick changes.

Unit	Symbol	Definition
Nanosecond	ns	A nanosecond (ns) is one billionth of a second. CPU clock cycles and memory latencies are measured in nanoseconds.
Microsecond	µs	A microsecond (µs) is one millionth of a second, used for network latencies and high-speed electronics timing.
Millisecond	ms	A millisecond (ms) is one thousandth of a second. Web response times, video frame timing and reaction times are measured in milliseconds.
Second	s	The second (s) is the SI base unit of time, defined by the radiation frequency of the cesium-133 atom. All other time units derive from it.
Minute	min	A minute (min) is 60 seconds. The 60-based division of hours dates back to Babylonian mathematics.
Hour	h	An hour (h) is 60 minutes or 3,600 seconds — one 24th of a day. Work time, travel time and billing commonly use hours.
Day	d	A day (d) is 24 hours or 86,400 seconds — one rotation of the Earth. Calendar calculations and durations build on days.
Week	wk	A week (wk) is 7 days or 168 hours. Schedules, pregnancy tracking and project planning commonly count in weeks.
Month (average)	mo	An average Gregorian month is 30.44 days (2,629,746 seconds) — one twelfth of the average year. Individual calendar months range from 28 to 31 days.
Year (Gregorian)	yr	A Gregorian calendar year averages 365.2425 days (31,556,952 seconds), accounting for leap years. Common years have 365 days; leap years 366.
