Convert a frequency into every unit at once

Enter one value and a unit — hertz, kilohertz, megahertz, gigahertz, terahertz, or revolutions per minute — and read it back in every unit at once. Each input is reduced to a canonical value in hertz (1 kHz = 1000 Hz, 1 GHz = 1,000,000,000 Hz, 60 rpm = 1 Hz), then every output is derived from that base. Decimals are supported, but a frequency cannot be negative.
