Frequently Asked Questions
How many GHz are in 1 MHz?
One MHz equals 0.001 GHz. Going the other way, 1 GHz is 1,000 MHz — both are powers-of-ten multiples of the hertz.
Are rpm and Hz the same?
Not quite. rpm (revolutions per minute) is a rotational speed, while Hz measures cycles per second. Because one revolution is one cycle, 60 rpm = 1 Hz exactly — so 1 rpm is about 0.0167 Hz.
How are Hz and rad/s related?
rad/s is the angular frequency ω. Since ω = 2πf, 1 Hz equals exactly 2π rad/s ≈ 6.283 rad/s. The factor of 2π appears because one full cycle spans 2π radians.
What is a hertz?
The hertz (Hz) is the SI unit of frequency and means one cycle per second. 1 kHz is 1,000 Hz, 1 MHz is 1,000,000 Hz, and 1 GHz is 1,000,000,000 Hz.
Are these conversions exact?
Yes. Frequency conversions rest on fixed factors (powers of ten, plus 60 and 2π); the values are only rounded for readability.
