Capacitors are rated in which unit?

• A. Microfarad (μF)
• B. Nanofarad (nF)
• C. Farad (F)
• D. Picofarad (pF)

Answer: (A)

Capacitance is measured in farads, but that unit is often too large for common capacitor values. The microfarad, which is 10^-6 farad, is a convenient scale for many capacitors used in everyday circuitry, so most catalogs, schematics, and datasheets list capacitance in μF. While smaller values do appear in nanofarads or picofarads, the practical, widely used ratings you’ll encounter most often are in microfarads. That’s why μF is the best answer here.
