Convert Kilojoule per kilogram degree Celsius to Kilowatt-hour per kilogram kelvin
Convert Kilojoule per kilogram degree Celsius (kJ/(kg·°C)) to Kilowatt-hour per kilogram kelvin (kWh/(kg·K)) instantly and accurately.
Conversion Formula
kWh/(kg·K) = kJ/(kg·°C) × 0.0002777777778
About Kilojoule per kilogram degree Celsius
The kilojoule per kilogram degree Celsius (kJ/(kg·°C)) equals exactly 1 kJ/(kg·K) = 1000 J/(kg·K) since 1 °C = 1 K. The preferred notation in European process and chemical engineering where Celsius dominates. Often used interchangeably with kJ/(kg·K) in material datasheets. Water: 4.182 kJ/(kg·°C). 1 kJ/(kg·°C) = 1 kJ/(kg·K) = 1000 J/(kg·K).
About Kilowatt-hour per kilogram kelvin
The kilowatt-hour per kilogram kelvin (kWh/(kg·K)) equals exactly 3.6 × 10⁶ J/(kg·K). Used in large-scale thermal energy storage design - molten salt storage, geothermal reservoirs, and industrial heat banks - where energy is measured in megawatt-hours. 1 kWh/(kg·K) = 3.6 MJ/(kg·K) = 1000 Wh/(kg·K) = 3.6 × 10⁶ J/(kg·K).
