About Converting Farads to Microfarads
Farad and Microfarad both belong to the electricity family — voltage, current, resistance, power, or energy — units that show up constantly when working across the different standards used by household wiring (120V/240V depending on region), automotive electrical systems (12V/24V), and electronics design. Farad is most often used for capacitor ratings in electronics design.
Formula
microfarads = farads × 1000000
This factor comes from each unit's defined relationship to the category's base unit: 1 farad equals 1 base unit, and 1 microfarad equals 0.000001 base units, so dividing one by the other gives the direct farad-to-microfarad factor of 1000000.
Simple example
1 F × 1000000 = 1,000,000 uF
1 farad = 1,000,000 microfarads.
Real-world example
120 F × 1000000 = 120,000,000 uF
120 farads = 120,000,000 microfarads.

Understanding the Farad
Farad (F) measures electrical capacitance. The SI derived unit of electrical capacitance. One farad is an extremely large capacitance for practical electronics — most real-world capacitors are rated in microfarads (µF) or picofarads (pF). It is classified as a SI derived unit.
Where it's used: Universal — SI derived unit used worldwide
Uses of the Farad today
- Capacitor ratings in electronics design
- Circuit timing and filtering calculations
- Battery and supercapacitor energy-storage specifications
History of the Farad
The farad is named after Michael Faraday (1791–1867), an English scientist whose experiments established the laws of electromagnetic induction and electrolysis, laying much of the groundwork for practical electrical engineering.
Historical origin. Farad was not the invention of a single named person; it developed through the process described above.
Understanding the Microfarad (uF)
Microfarad is 0.000001 farad units.

Frequently asked questions
How many microfarads are in 1 farad?
1 farad equals 1,000,000 microfarads, using the exact defined conversion factor rather than an estimate.
How do I convert farad to microfarad?
Multiply the farad value by 1000000. The converter above does this instantly to whatever precision you set.
How do I convert microfarad back to farad?
Use the reverse factor: 1 microfarad equals 0.000001 farads. You can also use the swap control in the converter above to flip the direction instantly.
What is a farad?
Farad (F) measures electrical capacitance. The SI derived unit of electrical capacitance. One farad is an extremely large capacitance for practical electronics — most real-world capacitors are rated in microfarads (µF) or picofarads (pF). It is classified as a SI derived unit.
What is a microfarad?
Microfarad (uF) is a unit of electricity.
Is the farad to microfarad conversion exact?
Yes. Both farad and microfarad are defined by fixed standards rather than physical artifacts, so the factor of 1000000 used above is exact to as many digits as you choose to display.
Where is the farad still used today?
Universal — SI derived unit used worldwide
What's the difference between voltage, current, and resistance?
Voltage (volts) is the electrical potential difference driving current through a circuit. Current (amperes) is the rate of flow of electric charge. Resistance (ohms) is how much a component opposes that flow. They're related by Ohm's law (V = I × R), but they are distinct physical quantities, and this page converts between units of just one of them.
