Kelvin (symbol: K)
Scientific unit of temperature. Color temperature is measured on the Kelvin scale.
| Conversion from | to | Formula | |
|---|---|---|---|
| kelvins | degrees Celsius | °C = K − 273.15 | |
| degrees Celsius | kelvins | K = °C + 273.15 | |
| kelvins | degrees Fahrenheit | °F = K × 1.8 − 459.67 | |
| degrees Fahrenheit | kelvins | K = (°F + 459.67) / 1.8 |
Kilowatt Hour (kWh)
KWH. A unit of measurement for electrical energy. One kilowatt hour equals 1000 watts of energy used for one hour.Kilowatt Demand Limiting / KW Demand Limiting
An energy management strategy that reduces energy consumption when a system's electric power meter exceeds an operator-defined threshold.
When power consumption exceeds defined levels, the system automatically adjust setpoints, de-energizes low priority equipment, and takes other pre-programmed actions to avoid peak demand charges. As the demand drops, the system restores loads in a predetermined manner.
