About the d to min calculation
One day is exactly 1,440 minutes, so converting between them is a single multiplication. Enter any value above and the result updates as you type. Twenty-four hours, or 86,400 seconds — one full rotation of the Earth relative to the Sun. Sixty seconds. The minute and the hour are the last widely used non-decimal units in science.
Formula
min = d × 1,440
1 d = 1,440 min
1 min = 0.00069444 dWorked example
To convert 30 d, multiply by 1,440: 30 × 1,440 = 43,200 min.
Frequently asked questions
How many minutes are in a day?
There are 1,440 minutes in one day. To convert any amount, multiply the number of days by 1,440.
How do I convert minutes back to days?
Divide instead of multiplying, or equivalently multiply by 0.00069444. One minute is 0.00069444 days.
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?
Days: twenty-four hours, or 86,400 seconds — one full rotation of the Earth relative to the Sun. Minutes: sixty seconds. The minute and the hour are the last widely used non-decimal units in science.
