Frequently asked questions
What is the source unit in this conversion?
The source unit is the zeptowatt (zW). A zeptowatt is 1e-21 watt units.
What is the destination unit in this conversion?
The destination unit is the milliwatt (mW). A milliwatt is 0.001 watt units.
How do I convert zeptowatts to milliwatts?
Multiply the zeptowatt value by 1e-18 to get milliwatt. For example, 1000 zW × 1e-18 = 1e-15 mW.
Is the zeptowatts to milliwatts conversion exact?
Yes. Both units are defined by fixed numeric relationships to the watt, so the conversion factor used here, 1e-18, is exact.
Where is this conversion commonly used?
It is used when comparing power ratings expressed in zeptowatts against equipment, engines, or specifications rated in milliwatts.
Can I convert milliwatts back to zeptowatts?
Yes. Multiply the milliwatt value by 1e+18 to get zeptowatt.

About this conversion
This page converts zeptowatts (zW) into milliwatts (mW), two units used to describe power, the rate at which energy is transferred or work is done.
A zeptowatt is 1e-21 watt units.
A milliwatt is 0.001 watt units.
The formula is mW = zW × 1e-18, derived from each unit's fixed relationship to the watt, the SI unit of power.
Because both units are defined by exact numeric relationships to the watt, this conversion is exact rather than approximate.
