Time Units Converter

Time Units Converter lets you convert time units through the second: value × source factor / target factor. Enter your own values or load the worked example.

Method and calculation

Convert time units through the second: value × source factor / target factor. Factors relative to second: ns = 1e-9; µs = 0.000001; ms = 0.001; s = 1; min = 60; h = 3600; day = 86400; week = 604800.

Inputs and settings

Time Units Converter accepts Value (minimum 0); From unit (ns, µs, ms, s, min, h, day, week); To unit (ns, µs, ms, s, min, h, day, week).

Worked example

Time Units Converter example — Value: 1; From unit: "ns"; To unit: "µs". Computed output: { "value": 0.001, "unit": "µs", "baseValue": 1e-9, "baseUnit": "second" }

Output and limitations

The duration table uses fixed seconds, minutes, hours, days and weeks. Calendar months and years are excluded because their lengths depend on dates and conventions. A day here is exactly 86400 seconds rather than a local daylight-saving interval.

Time Units Converter FAQs

Time Units Converter applies the following rule to your input: Convert time units through the second: value × source factor / target factor. The worked example on this page uses the same processor as the result button.
Time Units Converter has these boundaries: The time units factors are fixed conversions. Unit labels specify the convention; no live data is fetched. Start by checking the value field against the units or format shown.
Time Units Converter provides this sample: { "value": 0.001, "unit": "µs", "baseValue": 1e-9, "baseUnit": "second" }. Use the sample button to reproduce it, then replace the inputs with your own values.
