A milliwatt is one thousandth of a watt and commonly measures low power levels in electronic and optical devices.

When should I use deciwatts instead of milliwatts?

Deciwatts are useful when representing small power levels in a scale of one tenth of a watt, simplifying numerical expressions in scientific contexts.

How do I convert milliwatts to deciwatts?

Multiply the milliwatt value by 0.01 to get the equivalent power in deciwatts.
