Convert durations between microseconds and decades. This is handy for project planning, timesheets, cooking, science and software timing. Months are treated as 30 days and years as 365 days, so the conversions are consistent and easy to check.
Working with signals or cycles? See the frequency converter, and for movement over time the speed converter.
Turn task estimates in hours into working days, weeks or months for schedules and quotes.
Convert minutes to decimal hours (45 minutes = 0.75 hours) for timesheets and invoices.
Move between milliseconds, seconds and days when working with timers, logs and experiments.
Real months last 28-31 days and years may have 366 days. This tool uses fixed 30-day months and 365-day years; for exact dates use a calendar calculation.
Divide minutes by 60. So 90 minutes is 1.5 hours and 20 minutes is 0.3333 hours.
There are 86,400 seconds in a day (24 hours × 60 minutes × 60 seconds).
A week has 168 hours (7 days × 24 hours).
Divide the number of minutes by 60. For example, 150 minutes is 2.5 hours.
To keep conversions consistent, one month is fixed at 30 days and one year at 365 days. A calendar year is 365.2425 days on average.
