Electrical Unit Converters
Every electrical unit converters calculator on CalcEngines — unit converters, derived indices and interpretive tools, each with its formula, a worked example and the reference intervals it is judged against.
4 calculators in this section
- BTU to Watts Converter (and Tons of Refrigeration)BTU/h, watts, kilowatts, tons of refrigeration and kcal/h, all five at once and all from exact constants — 1 BTU/h = 0.29307107 W and 1 ton = 12,000 BTU/h = 3,516.85 W — with a table of the common air-conditioner sizes.
- Capacitance Converter (pF, nF, µF)Convert a capacitance between picofarads, nanofarads, microfarads, millifarads and farads — or start from the three-digit code printed on the part — and see the value in every unit at once, with the three-digit marking and the reactance at a frequency you choose.
- HP to kW ConverterConvert horsepower to kilowatts and back — with all three definitions kept apart, because mechanical, metric and electrical horsepower differ by 1.4% and a motor nameplate means one of them.
- mAh to Wh Converter (and Wh to mAh)Convert battery capacity between mAh, Ah and watt-hours at a stated cell voltage, with the energy in kWh and joules — and what a power bank really delivers at 5 V.
