Formula used
One microfarad equals one million picofarads. Divide picofarads by 1,000,000 for microfarads. Reverse conversion multiplies microfarads by exactly one million picofarads.
µF = pF ÷ 1,000,000 pF = µF × 1,000,000

Capacitor code guide
A three-digit code uses two significant digits first. The third digit gives the number of added zeros. Code 104 therefore represents 100,000 picofarads or 0.1 microfarads.
| Letter | Tolerance | Example |
|---|---|---|
| F | ±1% | 104F |
| G | ±2% | 104G |
| J | ±5% | 104J |
| K | ±10% | 104K |
| M | ±20% | 104M |
Frequently asked questions
How many pF are in one µF?
One microfarad contains exactly 1,000,000 picofarads. This relationship follows standard SI capacitance prefixes. Multiply microfarads by one million to obtain picofarads directly.
How do I convert pF to µF?
Divide the picofarad value by 1,000,000. The calculator performs this operation automatically. It also displays equivalent values across six capacitance units.
Can I convert µF back to pF?
Yes, select microfarads as the source unit. Select picofarads as the destination unit. The calculator multiplies your value by one million automatically.
What does capacitor code 104 mean?
The first two digits are significant figures. The third digit adds four zeros. Therefore, 104 means 100,000 pF, equalling 0.1 µF exactly.
What is engineering notation?
Engineering notation uses exponents divisible by three. It aligns naturally with common SI prefixes. This format makes electronic component values easier to compare.
What are E-series capacitor values?
E-series values distribute preferred components across each decade. Higher series numbers offer more available values. The nearest-value tool helps choose practical replacement capacitors quickly.
How does capacitor tolerance affect value?
Tolerance defines the permitted variation from nominal capacitance. A five-percent capacitor may vary above or below. This calculator displays both minimum and maximum expected values.
Can I enter scientific notation?
Yes, values like 1e5 are accepted. This equals 100,000 in standard notation. Scientific input helps manage extremely small or large values.
Why are trailing zeros removed?
Unneeded zeros can make simple values harder to read. The calculator removes them from standard results. Selected precision still controls available digits when they matter.
Can I download the calculation?
Yes, CSV and PDF export buttons are included. Printing is also available for paper records. The copy button places one complete result block conveniently.
Is this calculator suitable for electronics work?
It supports common units, codes, tolerances, and preferred series. Those tools suit design and component checking. Always verify voltage rating and dielectric requirements separately too.
