How the formula works
Both attowatt and hectowatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in attowatts by 1.000000e-20 to get hectowatts. To reverse the conversion, multiply a hectowatt value by 1.000000e+20 to get back to attowatts.
Frequently asked questions
What is Attowatt (aW)?
An Attowatt (aW) equals 1e-18 watt(s), a scaled unit of electrical power used for atto-scale electrical work.
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 attowatts to hectowatts?
Multiply the attowatt value by 1.000000e-20 to get the equivalent in hectowatts. For example, 5 aW × 1.000000e-20 = 5.000000e-20 hW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-20 is an exact, non-rounded value.
Can I convert hectowatts back to attowatts?
Yes. Divide the hectowatt value by 1.000000e-20, or multiply it by 1.000000e+20, to get attowatts.
