Unit conversion
Time Converter
Convert elapsed durations between nanoseconds, milliseconds, seconds, minutes, hours, days, and weeks.
Convert a value
Your values are processed in your browser and are not uploaded to ToolPixels. This tool does not save them.
Elapsed durations, not calendar dates
Enter a duration as a decimal number. For example, 1 hour 30 minutes is 1.5 hours or 90 minutes. Clock notation such as 1:30 is not accepted.
A day is exactly 24 hours and a week is 7 such days here. Calendar months and years are omitted because their lengths vary. This is not a time-zone or daylight-saving converter.
Example
90 minutes = 1.5 hours.
Precision and input limits
Results use browser floating-point arithmetic and are rounded to your selected number of significant digits, not decimal places. Small or large results may use scientific notation. This is not an arbitrary-precision calculator.
Enter zero or a number with magnitude from 1e-100 to 1e100. Signed values are supported for mathematical conversions. Swap units exchanges the unit choices without changing your input. Editing an input clears the previous result.
