Frequently Asked Questions
What does BTU stand for?
BTU stands for British Thermal Unit. It is commonly used in heating and air conditioning to measure the energy required to heat or cool a space.
What is the difference between Watts and Kilowatts?
A Kilowatt (kW) is simply 1,000 Watts. Most home appliances are measured in Watts, while industrial equipment is measured in Kilowatts.
Why is Kilowatts (kW) commonly used for electric cars?
Electric vehicles use kW instead of Horsepower to measure engine output because they run entirely on electrical systems, making kW a more accurate representation of their power.
