Microamperes to Milliamperes

1 microampere = 0.001 milliamperes · 1 mA = 1,000 µA

1 microampere = 0.001 milliamperes

How it’s calculated

mA = µA × 0.001

  • Multiply the value in microamperes by 0.001.
  • To go back, divide by 0.001 (or multiply by 1000).
  • 1 µA = 0.001 mA · 1 mA = 1,000 µA

  1. Find the conversion factor

    By definition 1 µA = 0.000001 A and 1 mA = 0.001 A, so 1 mA = 1000 µA. Source: BIPM SI Brochure (9th ed.) (SI prefixes and accepted units).

  2. Multiply by the factor written as a fraction

    Put µA in the denominator so it cancels, leaving mA.

  3. Calculate (unrounded)

  4. Round the answer

    Rounded to 5 significant figures.

Answer: 0.001 mA
