ProcirelCeramic and film capacitors often have a 3-digit code printed on them instead of the full value. The first two digits are significant figures, and the third digit is the multiplier (power of 10). The result is in picofarads (pF). This calculator converts the code to pF, nF, and µF instantly.
Capacitance (pF) = (1st digit × 10 + 2nd digit) × 103rd digitExample: Code 104 = 10 × 104 = 100,000 pF = 100 nF = 0.1 µF

How to use this calculator
Step-by-Step Instructions
1. **Find the 3-digit code** Look at the capacitor body for a printed 3-digit number (e.g., 104, 473, 222).
2. **Enter the code** Type the three digits exactly as printed. Do not include any letters or voltage ratings.
3. **Click Decode** The calculator shows the capacitance value in picofarads (pF), nanofarads (nF), and microfarads (µF).
Common Codes Reference
104 = 100nF (0.1µF) | 103 = 10nF | 473 = 47nF | 222 = 2.2nF | 101 = 100pF
