Enter the time value and units you want to convert from, then choose the time unit you want to convert to. You can convert between seconds, milliseconds, microseconds, nanoseconds, days, hours, weeks, months, and years.

Months in this time conversion calculator are calculated using the average of 30.416 days per month. This is equal to 365 days per year divided by 12 months per year. 365 ÷ 12 = 30.416 days per month.

Years in this time converter are calculated as 365 days per year. This calculator does not consider the extra day in a leap year which has 366 days per year.

How to Convert Units of Time

You can use conversion factors to convert a unit of time into another using multiplication or division. By knowing the conversion factor, converting between units can become a simple math problem:

S * C = E

Where S is the starting value, C is the conversion factor, and E is the converted result.

Conversions with Seconds

The table contains conversion factors to convert any time value into seconds using multiplication.

Example: Convert 120 Minutes into Seconds

Multiply 120 minutes by 60 seconds per minute

120 min * 60 s/min = 7200 seconds

Example: Convert 28,800 Seconds into Hours

1. Multiply 28,800 seconds by 1/3600 hours per second

2. This is the same as dividing 28,800 seconds by 3600 seconds per hour

28,800 s ÷ 3600 s/h = 8 hours

To convert among any units in the left column, say from A to B, you can multiply by the factor for A to convert A into seconds then divide by the factor for B to convert out of seconds. Or you can find the simplified factor by dividing the conversion factor for A by the conversion factor for B.

To convert from minutes to hours multiply the number of minutes by 60 and then divide by 3600. Simplified, this is the same as multiplying by 60/3600 which is 0.016666667. To convert directly from minutes to hours you multiply by 0.016.
