About Revolution (rev)
How do I convert revolutions to degrees?
Formula: Degrees = Revolutions × 360
Examples:
- 1 revolution = 360°
- 0.5 revolutions = 180°
- 2 revolutions = 720°
- 0.25 revolutions = 90°
- 10 revolutions = 3600°

How do I convert revolutions to radians?
Formula: Radians = Revolutions × 2π ≈ Revolutions × 6.2832
Examples:
- 1 revolution = 2π ≈ 6.283 radians
- 0.5 revolutions = π ≈ 3.142 radians
- 2 revolutions = 4π ≈ 12.566 radians
- 0.25 revolutions = π/2 ≈ 1.571 radians

What does RPM mean?
RPM = Revolutions Per Minute - a unit of rotational speed.
Formula: RPM = (Revolutions completed) ÷ (Time in minutes)
Common conversions:
- RPS (revolutions per second): 1 RPS = 60 RPM
- Angular velocity (rad/s): ω = RPM × (2π/60) ≈ RPM × 0.1047
- Angular velocity (°/s): ω = RPM × 6
Examples:
- 3000 RPM = 50 revolutions per second
- 1800 RPM = 30 revolutions per second = 188.5 rad/s
- 60 RPM = 1 revolution per second = 6.28 rad/s
How do I calculate wheel revolutions from distance?
Formula: Revolutions = Distance ÷ (Circumference of wheel)
Circumference: C = π × diameter = 2π × radius
Example calculations:
Car tire (diameter = 24 inches = 0.61 meters):
- Circumference = π × 0.61 = 1.92 meters
- Distance = 1 km = 1000 meters
- Revolutions = 1000 ÷ 1.92 = 521 revolutions
Bicycle wheel (26-inch diameter):
- Circumference = π × 0.66 = 2.07 meters
- Distance = 10 km = 10,000 meters
- Revolutions = 10,000 ÷ 2.07 = 4,831 revolutions
Practical application: Odometers use wheel revolutions to calculate distance traveled.
About Arcsecond (″)
How do I convert arcseconds to degrees?
Formula: Degrees = Arcseconds ÷ 3600
Examples:
- 3600 arcseconds = 1°
- 1800 arcseconds = 0.5°
- 60 arcseconds = 1 arcminute = 0.0167°
- 1 arcsecond ≈ 0.000278°

How do I convert arcseconds to arcminutes?
Formula: Arcminutes = Arcseconds ÷ 60
Examples:
- 60 arcseconds = 1 arcminute
- 120 arcseconds = 2 arcminutes
- 30 arcseconds = 0.5 arcminutes
- 3600 arcseconds = 60 arcminutes = 1°

How big is 1 arcsecond on Earth's surface?
At the equator: 1 arcsecond ≈ 30.9 meters ≈ 101 feet
Latitude (north-south): Always ≈ 30.9 m per arcsecond Longitude (east-west): Varies by latitude:
- Equator: 30.9 m
- 45° latitude: 21.9 m
- 60° latitude: 15.5 m
- 80° latitude: 5.4 m
This is why GPS coordinates to arcsecond precision give location within ~30 meters.
What is stellar parallax in arcseconds?
Stellar parallax is the apparent shift in a star's position as Earth orbits the Sun, measured in arcseconds.
Formula: Distance (parsecs) = 1 / Parallax (arcseconds)
Examples:
- Proxima Centauri: 0.768 arcseconds → 1.30 parsecs (4.24 light-years)
- Sirius: 0.379 arcseconds → 2.64 parsecs (8.6 light-years)
- Alpha Centauri A: 0.742 arcseconds → 1.35 parsecs (4.37 light-years)
- Barnard's Star: 0.547 arcseconds → 1.83 parsecs (5.96 light-years)
The parsec (pc) unit was defined as the distance at which 1 AU creates 1 arcsecond parallax.
