- 1 rev = 1296000 ″
- 1 × 1296000 = 1296000 ″
How to convert revolutions to seconds of arc
1 rev = 1,296,000 ″, so multiply by 1,296,000 to go from revolutions (turns) to seconds of arc. Going the other way, 1 ″ = 7.71604938272 × 10⁻⁷ rev.
″ = rev × 1,296,000 rev = ″ × 7.71604938272
Worked example:
1 rev = 1296000 ″ 5 × 1296000 = 6480000 ″

About the units
- Revolutions (rev)
- Revolutions (turns), a specialised unit. Involves π, which no fraction equals exactly; this converter uses π to 50 significant digits, far beyond the 12 digits shown. Definition: NIST SP 811 Appendix B.8, factors for units listed alphabetically.
- Seconds of Arc (″)
- Seconds of arc, a metric unit. Involves π, which no fraction equals exactly; this converter uses π to 50 significant digits, far beyond the 12 digits shown. Definition: BIPM SI Brochure, 9th edition (SI units, prefixes and units accepted for use with the SI).
