How does this calculator work?
Capacitance units follow the SI prefix system with factors of 1,000: 1 F = 10³ mF = 10⁶ µF = 10⁹ nF = 10¹² pF = 10¹⁵ fF. Enter any value and choose from/to units to convert instantly. Most practical capacitors fall between 1 pF and 10,000 µF.
Formula
How this is calculated
Capacitance is measured in farads (F), but practical capacitors span fifteen orders of magnitude — from femtofarad semiconductor parasitic capacitances to several-farad supercapacitors used in energy storage. Each prefix step is a factor of 1,000: 1 F = 1,000 mF = 1,000,000 µF = 10⁹ nF = 10¹² pF = 10¹⁵ fF.
The converter anchors every unit to its factor relative to one farad. To convert, it first multiplies the input by the source unit's factor to express the value in plain farads, then divides by the target unit's factor. The result is exact (floating-point precision limited): 100 µF = 100 × 10⁻⁶ F = 100,000 nF = 100,000,000 pF.
The log-scale bar shows where the value sits across the full range of common capacitor values. Most small-signal electronics use picofarad to nanofarad capacitors; bypass and decoupling capacitors are typically 100 nF to 10 µF; large electrolytic capacitors for power supplies are 100 µF to several mF.
Frequently asked questions
There are 1,000 nanofarads (nF) in one microfarad (µF). Each step in the SI prefix chain (µF → nF → pF → fF) represents a factor of 1,000.
One farad is a very large capacitance — a 1 F capacitor would need plates of enormous area. Practical capacitors in electronics range from a few picofarads (RF/tuning circuits) to thousands of microfarads (power supply filtering), so the smaller SI prefixes are used for convenience.
Femtofarad (fF) capacitances appear in semiconductor physics — gate capacitances in MOSFETs, parasitic capacitances on PCB traces, and MEMS sensors. At these scales, stray capacitance from wiring can be significant and must be modelled carefully in high-frequency designs.
