How it is calculated
- Every value is first converted to seconds, then into the unit you choose
- 1 minute = 60 s, 1 hour = 3,600 s, 1 day = 86,400 s, 1 week = 604,800 s
- 1 year = 365 days = 31,536,000 s
To convert hours and minutes to a decimal, use the time to decimal calculator.
Worked example
90 minutes:
- = 1.5 hours
- = 5,400 seconds
Why your number may differ
Months are not included because they have 28 to 31 days. For calendar spans between two dates, use the date difference calculator instead.
