How to Convert RPM to RPS (Revolution/min to Revolution/s)?

We can convert revolution/min to revolution/s by using an example.

Example:

Convert 20 Revolution/min to Revolution/s?

We know 1 Revolution/min = 0.0166667 revolution/s; 1 Revolution/s = 59.9998090 revolution/min.

20 revolution/min = ___rps

20 × 0.0166667 = 0.33333 rps (we know 1 revolution/min = 0.0166667 revolution/s)

Answer:

20 revolution/min = 0.33333 revolution/s

RPM to RPS: Revolutions per Minute to Revolutions per Second

Converting RPM to RPS (revolutions per second) is one of the simplest angular velocity conversions — just divide by 60. RPS is useful when you need to calculate how many complete turns happen each second, which is often more intuitive for high-speed applications like hard drives, turbines, and centrifuges.

  1. Take the rotational speed in revolutions per minute (RPM).
  2. Divide by 60 (since there are 60 seconds in a minute).
  3. The result is revolutions per second (RPS).
  4. Also written as Hz (hertz) in some contexts, since 1 RPS = 1 Hz of rotation.
💡 Tip: RPS is sometimes called rotational frequency and can be expressed in hertz. A 3,600 RPM motor runs at exactly 60 RPS (60 Hz) — the same frequency as US power grids, which is not a coincidence for synchronous motors.

Solved: RPM to RPS Conversions

Question 1: A blender motor runs at 24,000 RPM. How many revolutions per second?

Solution:

RPS = RPM ÷ 60

= 24,000 ÷ 60

= 400 RPS

Answer: 24,000 RPM = 400 RPS — the blade completes 400 full rotations every second.

Question 2: A ceiling fan rotates at 180 RPM. Convert to RPS.

Solution:

RPS = RPM ÷ 60

= 180 ÷ 60

= 3 RPS

Answer: 180 RPM = 3 RPS — three full turns per second at high speed.

Question 3: A car engine idles at 750 RPM. What is that in RPS?

Solution:

RPS = RPM ÷ 60

= 750 ÷ 60

= 12.5 RPS

Answer: 750 RPM = 12.5 RPS — the crankshaft turns 12.5 times each second at idle.

Try solving these on your own to test your understanding:

  1. Convert 3,000 RPM to RPS. (Answer: 50 RPS)
  2. A drill spins at 2,400 RPM. What is that in RPS? (Answer: 40 RPS)
  3. Convert 10,000 RPM to RPS. (Answer: 166.67 RPS)
  4. A turntable rotates at 33.33 RPM. Express in RPS. (Answer: 0.556 RPS)
  5. Convert 600 RPM to RPS. (Answer: 10 RPS)

RPS, Hz, and Frequency: The Same Thing?

Technically, 1 RPS = 1 Hz (hertz), since hertz measures cycles per second. However, using Hz for rotation can cause confusion with electrical frequency. In practice, RPS is preferred for mechanical rotation while Hz is used for oscillation and AC frequency. When a spec sheet says a motor runs at "60 Hz," it might mean electrical supply frequency, not rotational speed — context matters.

From RPS to Linear Speed

If you know RPS and the radius, you can calculate linear (tangential) speed: v = 2π × r × RPS. For example, a wheel with 0.3 m radius at 10 RPS gives: v = 2π × 0.3 × 10 = 18.85 m/s (about 68 km/h). This is useful for calculating vehicle speed from wheel RPM, conveyor belt speed, or grinding wheel surface speed.

Key Takeaways

  • Divide RPM by 60 to get RPS.
  • 1 RPS = 60 RPM = one complete revolution per second.
  • RPS is numerically equal to Hz (rotational frequency).
  • Hard drives: 5,400 RPM = 90 RPS, 7,200 RPM = 120 RPS.
  • Linear speed from RPS: v = 2πr × RPS (m/s when r is in meters).

Revolution/min to Revolution/s Conversion Formula

revolution/s = revolution/min × 0.0166667

1 revolution/min = 0.0166667 revolution/s

1 revolution/s = 59.9998090 revolution/min

Reverse: revolution/min = revolution/s × 59.9998090
