Milliwatt to Volt-Ampere (VA) Converter
Power · unit-converter
Convert Milliwatt to Volt-Ampere (VA) 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 Milliwatt
One milliwatt is one thousandth of a watt. Common in RF, fiber optics, and low-power electronics.
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.
How to convert milliwatts to volt-amperes (va, unity pf)
1 milliwatt is equal to 0.001 volt-ampere (va) when both are expressed in watt-equivalents:
1 mw = (0.001 W ÷ 1 W) va = 0.001 va
Each milliwatt is defined as 0.001 W and each volt-ampere (va) as 1 W in this tool, so one mw equals 0.001 ÷ 1 va = 0.001 va.
Let d(mw) be the numeric value in Milliwatt (mw), and d(va) the value in Volt-Ampere (VA) (va). Then:
d(va) = d(mw) × (0.001 / 1)
Equivalently, divide by how many mw fit into one va (watts per va divided by watts per mw):
d(va) = d(mw) ÷ 1000
Or: volt-ampere (va) = milliwatt ÷ 1000
Examples
Example #1: Convert 1 mw to volt-ampere (va)
1 mw = 1 mw × (0.001/1) va = 0.001 va
1 mw = 1 mw ÷ 1000 = 0.001 va
Intermediate watts: 0.001 W
Example #2: Convert 10 mw to volt-ampere (va)
10 mw = 10 mw × (0.001/1) va = 0.01 va
10 mw = 10 mw ÷ 1000 = 0.01 va
Intermediate watts: 0.01 W
Summary
To convert Milliwatt to Volt-Ampere (VA), multiply the value in mw by the ratio of watts per mw divided by watts per va. Equivalently: value_va = value_mw × (0.001 / 1). Numerically, 1 mw equals 0.001 va.
Relationship context
You are converting between SI / decimal power (watts and prefixes) (Milliwatts) and apparent power at unity PF (VA) (Volt-Amperes (VA, unity PF)). All linear values are mapped through watts first. The numeric factor is 1.000000e-3.
