Frequency converters

10 converters. Hertz, kilohertz, megahertz, gigahertz and RPM, each with the formula and the math worked out with your numbers.

Frequency

Kilohertz to hertz kHz → Hz 2.5 kHz = 2,500 Hz Hertz to kilohertz Hz → kHz 44,100 Hz = 44.1 kHz Megahertz to gigahertz MHz → GHz 2,400 MHz = 2.4 GHz Gigahertz to megahertz GHz → MHz 5 GHz = 5,000 MHz Kilohertz to megahertz kHz → MHz 1,500 kHz = 1.5 MHz Megahertz to kilohertz MHz → kHz 1.2 MHz = 1,200 kHz

Rotation

Revolutions per minute to hertz rpm → Hz 3,000 rpm = 50 Hz Hertz to revolutions per minute Hz → rpm 50 Hz = 3,000 rpm Revolutions per minute to radians per second rpm → rad/s 1,000 rpm = 104.72 rad/s Radians per second to revolutions per minute rad/s → rpm 100 rad/s = 954.93 rpm
