Enerji
Joule, kJ, cal, kcal, kWh, BTU dönüştür
Nedir?
Energy is the capacity of a system to produce work, heat, or radiation. It is a fundamental physical quantity conserved in all physical processes (first law of thermodynamics). Energy manifests in many forms: kinetic, potential, thermal, electrical, chemical, and nuclear. Converting between energy units is essential in thermodynamics, nutrition, electricity, and energy engineering.

Birim rehberi
Joule (J)
SI unit of energy. One Joule is the work done by a force of one Newton over a distance of one meter.
Kilojoule (kJ)
One thousand Joules. Used in nutrition (European food labels) and thermodynamics.
Calorie (cal)
Amount of heat needed to raise the temperature of one gram of water by 1°C. Foundation of thermochemistry.
Kilocalorie (kcal)
One thousand calories. The food "Calorie". Used universally in nutrition and dietetics.
Kilowatt-hour (kWh)
Electrical energy unit billed by power companies. 1 kWh = 3.6 MJ.
BTU (British Thermal Unit)
Anglo-Saxon heat unit. Used in HVAC and North American oil and gas industries.
