How to Convert Revolution to Arcminute
- 1 rev = 21600 ′
- 1 ′ = 0.0000462962963 rev
- Example: convert 15 rev to ′: 15 rev = 15 × 21600 ′ = 324000 ′
Formula
′ = rev × 21600
Derivation from SI units:
- 1 revolution = 2π rad = 360°.
- 1′ = (1/60)° = π/10 800 rad.
- 1 rev = 6.28318530718 rad ÷ 0.0002908882086657 rad per ′ = 21600 ′
Both units are defined exactly, so the factor is exact. Revolution definition: revolution; Arcminute definition: minute of arc.
Worked examples
- A reading of 1 rev converts to 21600 ′.
1 rev × 21600 = 21600 ′ - A value of 3 rev is 64800 ′.
3 rev × 21600 = 64800 ′
