What Is This Tool?
This tool converts between time units — from milliseconds to years. It uses precise factors for small units (seconds, minutes, hours, days) and averages for months and years, since those vary in length.
Standard Conversions
- 1 minute = 60 seconds
- 1 hour = 60 minutes = 3,600 seconds
- 1 day = 24 hours = 1,440 minutes
- 1 week = 7 days = 168 hours
- 1 year ≈ 365.25 days (accounts for leap years)
Months Are Tricky
Months vary from 28 to 31 days, so there's no exact conversion. This tool uses the average of 30.44 days per month (365.25 ÷ 12). For precise date math, use the Date Difference Calculator instead.
Common Uses
- Converting running pace (min/km to min/mi)

About the Time Converter
The Time Converter converts time converterfrom one unit to another using the exact internationally defined conversion factors. Type a value, choose your source and target units, and the converted result is shown instantly — no waiting, no page reload.
Manual conversion is error-prone because it means memorizing ratios (how many feet in a meter, how many pints in a liter). This tool removes that friction: the conversion factor is built in, and the math is done to full precision with no rounding until the final displayed number.
