How the formula works
Both microwatt and watt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in microwatts by 0.000001 to get watts. To reverse the conversion, multiply a watt value by 1.000000e+06 to get back to microwatts.
Frequently asked questions
What is Microwatt (uW)?
A Microwatt (uW) equals 1e-06 watt(s), a scaled unit of electrical power used for micro-scale electrical work.
What is Watt (W)?
The watt (W) is the SI unit of power, equal to one joule of energy transferred per second.
How do I convert microwatts to watts?
Multiply the microwatt value by 0.000001 to get the equivalent in watts. For example, 5 uW × 0.000001 = 0.000005 W.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 0.000001 is an exact, non-rounded value.
Can I convert watts back to microwatts?
Yes. Divide the watt value by 0.000001, or multiply it by 1.000000e+06, to get microwatts.
