Convert kilowatt [kW] to Btu (th)/hour [Btu (th)/h] Online | Free power Converter

Kilowatt (kW)

The kilowatt (symbol: kW) is a unit of power in the International System of Units (SI) equal to 1,000 watts:

Kilowatts are widely used to measure the power consumption or output of household appliances, small engines, and electric tools. For example, a typical microwave oven might use about 1 kW of power.

In electricity billing, power usage is often measured in kilowatt-hours (kWh), which reflects energy consumption over time.

The kilowatt is a practical unit for everyday energy use, bridging the scale from watts (for small devices) to megawatts (for larger power generation). It helps people understand and compare the power ratings of common electrical equipment.

Btu (th)/hour [Btu (th)/h]

The Btu (th)/hour stands for British thermal unit (thermochemical) per hour and is a unit of power measuring the rate of heat transfer.

• 
  

  Btu (th) or thermochemical Btu is a slightly different standardized value of the British thermal unit, based on thermochemical measurements. It is defined as approximately 1,055.87 joules, slightly less than the International Table (IT) Btu.

  
  
• 
  

  When expressed as Btu (th)/hour, it measures how many thermochemical Btus of heat energy are transferred or generated in one hour.

This unit is commonly used in scientific and engineering contexts where precise heat transfer rates are required, such as in thermodynamics and chemical processes.
