Unit Information
Btu_per_hour
A unit of power equal to one British Thermal Unit per hour. Commonly used in heating, ventilation, and air conditioning (HVAC) systems for measuring heating and cooling capacities.
Watt
The SI unit of power, defined as one joule per second. Named after Scottish engineer James Watt, it measures the rate of energy transfer or conversion in electrical, mechanical, and thermal systems.
Conversion Tips
- Remember to check your decimal places for accuracy.
- This conversion is commonly used in international applications.
- Consider the context when choosing precision levels.
- Double-check calculations for critical applications.
