How the formula works
Both watt and hectowatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in watts by 0.01 to get hectowatts. To reverse the conversion, multiply a hectowatt value by 100 to get back to watts.
Frequently asked questions
What is Watt (W)?
The watt (W) is the SI unit of power, equal to one joule of energy transferred per second.
What is Hectowatt (hW)?
A Hectowatt (hW) equals 100 watt(s), a scaled unit of electrical power used for hecto-scale electrical work.
How do I convert watts to hectowatts?
Multiply the watt value by 0.01 to get the equivalent in hectowatts. For example, 5 W × 0.01 = 0.05 hW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 0.01 is an exact, non-rounded value.
Can I convert hectowatts back to watts?
Yes. Divide the hectowatt value by 0.01, or multiply it by 100, to get watts.
