Volt-Ampere (VA) to Milliwatt Converter
Power · unit-converter
Convert Volt-Ampere (VA) to Milliwatt with a fixed input and output unit, step-by-step formula line, and reference tables. Linear units use SI watt definitions; mechanical hp uses 550 ft·lbf/s; BTU/h uses the IT BTU; dBm/dBW are logarithmic relative to 1 mW and 1 W. The full Power Converter also includes PS/CV, TR, kVA/MVA, and ft·lb/s.

About Volt-Ampere (VA)
Volt-amperes describe apparent power in AC circuits. At unity power factor, VA matches real power in watts; this tool uses that 1:1 mapping for conversion.
About Milliwatt
One milliwatt is one thousandth of a watt. Common in RF, fiber optics, and low-power electronics.
How to convert volt-amperes (va, unity pf) to milliwatts
1 volt-ampere (va) is equal to 1000 milliwatt when both are expressed in watt-equivalents:
1 va = (1 W ÷ 0.001 W) mw = 1000 mw
Each volt-ampere (va) is defined as 1 W and each milliwatt as 0.001 W in this tool, so one va equals 1 ÷ 0.001 mw = 1000 mw.
Let d(va) be the numeric value in Volt-Ampere (VA) (va), and d(mw) the value in Milliwatt (mw). Then:
d(mw) = d(va) × (1 / 0.001)
Equivalently, divide by how many va fit into one mw (watts per mw divided by watts per va):
d(mw) = d(va) ÷ 0.001
Or: milliwatt = volt-ampere (va) ÷ 0.001
Examples
Example #1: Convert 1 va to milliwatt
1 va = 1 va × (1/0.001) mw = 1000 mw
1 va = 1 va ÷ 0.001 = 1000 mw
Intermediate watts: 1 W
Example #2: Convert 10 va to milliwatt
10 va = 10 va × (1/0.001) mw = 10000 mw
10 va = 10 va ÷ 0.001 = 10000 mw
Intermediate watts: 10 W
Summary
To convert Volt-Ampere (VA) to Milliwatt, multiply the value in va by the ratio of watts per va divided by watts per mw. Equivalently: value_mw = value_va × (1 / 0.001). Numerically, 1 va equals 1000 mw.
Relationship context
You are converting between apparent power at unity PF (VA) (Volt-Amperes (VA, unity PF)) and SI / decimal power (watts and prefixes) (Milliwatts). All linear values are mapped through watts first. The numeric factor is 1.000000e+3.
