참고
Prefixes are exact by definition. They may not be compounded: a millionth of a metre is a micrometre, never a millimillimetre.

Length Converter
Convert PCB dimensions between millimetres, mils (thou), inches, micrometres, centimetres, and metres. Includes the copper-weight equivalent for plating thickness.
Frequency ↔ Wavelength
Convert frequency to wavelength instantly: 150 MHz = 2.0 m, 2.4 GHz = 12.5 cm, 5.8 GHz = 5.2 cm. Calculates full, half, and quarter wavelengths for any medium — antenna design, coax, and RF planning.
dBm ↔ Watts
Instant dBm ↔ watts conversion: 0 dBm = 1 mW, 10 dBm = 10 mW, 20 dBm = 100 mW, 30 dBm = 1 W. Also converts dBW, dBμV, and RMS volts for 50 Ω RF systems.
Capacitance Converter
Convert capacitance between farads, millifarads, microfarads, nanofarads, and picofarads.
