How the formula works
Both decawatt and attowatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in decawatts by 1.000000e+19 to get attowatts. To reverse the conversion, multiply a attowatt value by 1.000000e-19 to get back to decawatts.
Frequently asked questions
What is Decawatt (daW)?
A Decawatt (daW) equals 10 watt(s), a scaled unit of electrical power used for deca-scale electrical work.
What is Attowatt (aW)?
An Attowatt (aW) equals 1e-18 watt(s), a scaled unit of electrical power used for atto-scale electrical work.
How do I convert decawatts to attowatts?
Multiply the decawatt value by 1.000000e+19 to get the equivalent in attowatts. For example, 5 daW × 1.000000e+19 = 5.000000e+19 aW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+19 is an exact, non-rounded value.
Can I convert attowatts back to decawatts?
Yes. Divide the attowatt value by 1.000000e+19, or multiply it by 1.000000e-19, to get decawatts.
