Unit definition
Millifarads (mF) One millifarads equals 0.001 farad.
Unit history
Millifarads is represented here using its modern SI definition or an internationally accepted relationship to an SI base unit.
Step by step
1. Parse the value, including fractions.
2. Convert mF to farad.
3. Convert the base value to µF and apply your display precision.
Understand the result before using it
This converter changes millifarads (mF) to microfarads (µF). A millifarad is 10⁻³ F and a microfarad is 10⁻⁶ F, so 1 mF = 1,000 µF. Multiply the mF value by 1,000. Microfarads are also commonly typed as uF.
Calculated result
The conversion follows the displayed unit relationship. Display rounding can hide additional digits, and measured inputs cannot become more accurate merely by changing units.
Formula, assumptions, and example
Formula
result = input × 1000
Assumptions
- Millifarads and Microfarads represent the same capacitance quantity.
- The input is expressed in mF; the output is expressed in µF.
- The unit definitions and conventional relationship shown on this page apply.
Worked example
For 0.47 mF, calculate 0.47 × 1,000 = 470 µF. For 2.2 mF, calculate 2.2 × 1,000 = 2,200 µF.
When to use it
Good uses
- Put a capacitance expressed in mF into a worksheet that expects µF.
- Compare capacitance values that use milli and micro prefixes.
Limitations
Common mistakes to avoid
- This page uses mF for millifarads and µF or uF for microfarads; keep the two prefixes distinct.
- A conversion preserves the capacitance value and does not establish component compatibility.
- Retain only the precision supported by the original capacitance value.

Questions about this calculation
What is 1 mF in µF?
1 mF equals 1,000 µF. Multiply millifarads by 1,000 to obtain microfarads.
How do I convert 0.47 mF to uF?
uF is a typed form of µF. Calculate 0.47 × 1,000 = 470 µF.
How do I reverse µF to mF?
