How the formula works
Both hectowatt and gigawatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in hectowatts by 1.000000e-07 to get gigawatts. To reverse the conversion, multiply a gigawatt value by 1.000000e+07 to get back to hectowatts.
Frequently asked questions
What is Hectowatt (hW)?
A Hectowatt (hW) equals 100 watt(s), a scaled unit of electrical power used for hecto-scale electrical work.
What is Gigawatt (GW)?
A Gigawatt (GW) equals 1e+9 watt(s), a scaled unit of electrical power used for giga-scale electrical work.
How do I convert hectowatts to gigawatts?
Multiply the hectowatt value by 1.000000e-07 to get the equivalent in gigawatts. For example, 5 hW × 1.000000e-07 = 5.000000e-07 GW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-07 is an exact, non-rounded value.
Can I convert gigawatts back to hectowatts?
Yes. Divide the gigawatt value by 1.000000e-07, or multiply it by 1.000000e+07, to get hectowatts.
