How to Convert Day to Minute
- 1 d = 1440 min
- 1 min = 0.0006944444444 d
- Example: convert 15 d to min: 15 d = 15 × 1440 min = 21600 min
Formula
min = d × 1440
Derivation from SI units:
- 1 d = 24 h = 86 400 s
- 1 min = 60 s
- 1 d = 86400 s ÷ 60 s per min = 1440 min
Both units are defined exactly, so the factor is exact. Day definition: day; Minute definition: minute.
Worked examples
- 1 d equals 1440 min.
1 d × 1440 = 1440 min - A quarter of a day, 0.25 d, is 360 min.
0.25 d × 1440 = 360 min
