How the time units relate

These units relate by fixed, exact ratios: 1 minute = 60 seconds, 1 hour = 60 minutes = 3,600 seconds, 1 day = 24 hours = 86,400 seconds, and 1 week = 7 days = 604,800 seconds. In the millisecond range the decimal factor applies: 1 second = 1,000 milliseconds. There is no rounding and no leap-second assumption — every conversion is exact.

Months and years are deliberately left out: a month has 28–31 days and a year has 365 or 365.2425 days, so a fixed conversion would be misleading. Use our dedicated calculators for those — days in a month, days in a year and months to minutes. For more unit pairs, open the time conversion hub.

Frequently asked questions

How much is 1 day in hours?

How do I convert days to hours?

Are these time conversions exact?

Yes. These units have fixed, exact ratios: 1 minute = 60 seconds, 1 hour = 3,600 seconds, 1 day = 86,400 seconds, 1 week = 604,800 seconds, and 1 second = 1,000 milliseconds. There is no rounding and no leap-second assumption.

Why aren't months and years included here?

Months (28–31 days) and years (365 or 365.2425 days) don't have a fixed length, so a simple conversion would be misleading. For those, use our dedicated calculators: days in a month, days in a year, and months to minutes.

What are these time units used for?

Milliseconds and seconds measure short spans (reaction times, latency, sports). Minutes and hours structure the day (appointments, cooking, work). Days and weeks plan longer spans (projects, holidays, deadlines). All relate through the second by a fixed ratio.
