About the min to d calculation
One minute is exactly 0.00069444 days, so converting between them is a single multiplication. Enter any value above and the result updates as you type. Sixty seconds. The minute and the hour are the last widely used non-decimal units in science. Twenty-four hours, or 86,400 seconds — one full rotation of the Earth relative to the Sun.
Formula
d = min × 0.00069444
1 min = 0.00069444 d
1 d = 1,440 minWorked example
To convert 90 min, multiply by 0.00069444: 90 × 0.00069444 = 0.0625 d.
Frequently asked questions
How many days are in a minute?
There are 0.00069444 days in one minute. To convert any amount, multiply the number of minutes by 0.00069444.
How do I convert days back to minutes?
Divide instead of multiplying, or equivalently multiply by 1,440. One day is 1,440 minutes.
Is this conversion exact?
For seconds through weeks, yes — they are fixed multiples. The year is the mean Gregorian year of 365.2425 days, which is an average rather than the length of any particular calendar year.
Where is each of these units used?
Minutes: sixty seconds. The minute and the hour are the last widely used non-decimal units in science. Days: twenty-four hours, or 86,400 seconds — one full rotation of the Earth relative to the Sun.
