An RPM to radians per second converter converts rotational speed between revolutions per minute (RPM) — used for engines and motors — and rad/s, the SI unit for angular velocity.
Công thức
rad/s = rpm × (π / 30) ≈ rpm × 0.10472
- rpm
- Revolutions per minute (rpm) — Rotational speed unit
- rads
- Radians per second (rad/s) — SI angular velocity unit
Hướng dẫn từng bước
- 11 revolution = 2π radians
- 21 RPM = 2π ÷ 60 rad/s = 0.10472 rad/s
- 3rad/s = RPM × (2π ÷ 60)
- 4RPM = rad/s × (60 ÷ 2π)
Ví dụ có lời giải
đầu vào
1,000 RPM (engine idle)
Kết quả
104.72 rad/s
đầu vào
3,000 RPM (typical engine)
Kết quả
314.16 rad/s
đầu vào
60 RPM (1 revolution/second)
Kết quả
6.283 rad/s = 2π
Câu hỏi thường gặp
How many radians per second is 1,800 rpm?
1,800 rpm × 0.10472 ≈ 188.5 rad/s. A spindle or motor speed reference.
What is a radian?
One radian is the angle where arc length equals radius. 1 full rotation = 2π radians ≈ 6.283 rad.
Why do engineers use both rpm and rad/s?
rpm is intuitive for machinists; rad/s is SI standard for physics and control systems. Convert as needed.
