Convert Kilohertz to Revolutions per minute

1 kilohertz is 60,000 rpm. One kilohertz is exactly 60000 revolutions per minute.

One kilohertz is 60000 revolutions per minute. To convert kilohertz to revolutions per minute, multiply by 60000; to go the other way, divide by 60000 or multiply by 1.6667 × 10^-5. The factor is exact rather than rounded: it follows from NIST Special Publication 811. A thousand hertz.

Factors are entered by hand from NIST Special Publication 811 rather than derived from a units library, so the ones that terminate are exact rather than rounded.

How do you convert kilohertz to revolutions per minute? The converter and the working

  1. 1.Take the measurement in kilohertz.
  2. 2.Multiply by 60000 — that is how many revolutions per minute fit in one kilohertz.
  3. 3.To go back the other way, divide by 60000, or multiply by 1.6667 × 10^-5.

Worked example: 25 kilohertz to revolutions per minute

Formula
kHz × 60000 = rpm
Arithmetic
25 × 60000 = 1,500,000 rpm
Answer
25 kHz = 1,500,000 rpm

The factor is exact, so this figure is exact too — only the display is rounded.

What is a kilohertz?

A thousand hertz. AM radio is broadcast here — 540 to 1600 kHz — and audio sampling is quoted in it: a CD samples at 44.1 kHz.

What is a revolution per minute?

One turn a minute, so 60 rpm is 1 Hz. Engines, drills and hard drives are all rated in it: a 7,200 rpm drive spins at 120 Hz.

How many revolutions per minute are in a kilohertz?

One kilohertz is 60000 revolutions per minute, exactly. Going the other way, one revolution per minute is 1.6667 × 10^-5 kilohertz. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.

The whole group — 6 units with their symbols and the size of each one in hertzs — is on the conversion index, along with every pair it makes. The table above already gives each of them relative to a kilohertz.

Questions people actually ask

How many revolutions per minute are in a kilohertz?
60000. One turn a minute, so 60 rpm is 1 Hz. Engines, drills and hard drives are all rated in it: a 7,200 rpm drive spins at 120 Hz.
How do I convert revolutions per minute back to kilohertz?
Divide by 60000, or multiply by 1.6667 × 10^-5 — they are the same operation.

Other frequency conversions

Revolutions per minute to kilohertz — the same conversion the other way.
