How the formula works
Both nanowatt and terawatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in nanowatts by 1.000000e-21 to get terawatts. To reverse the conversion, multiply a terawatt value by 1.000000e+21 to get back to nanowatts.
Frequently asked questions
What is Nanowatt (nW)?
A Nanowatt (nW) equals 1e-09 watt(s), a scaled unit of electrical power used for nano-scale electrical work.
What is Terawatt (TW)?
A Terawatt (TW) equals 1e+12 watt(s), a scaled unit of electrical power used for tera-scale electrical work.
How do I convert nanowatts to terawatts?
Multiply the nanowatt value by 1.000000e-21 to get the equivalent in terawatts. For example, 5 nW × 1.000000e-21 = 5.000000e-21 TW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-21 is an exact, non-rounded value.
Can I convert terawatts back to nanowatts?
Yes. Divide the terawatt value by 1.000000e-21, or multiply it by 1.000000e+21, to get nanowatts.
