Select the quantity type (current, voltage, resistance, capacitance, or inductance), then enter a value and choose from/to units for instant conversion.
Ohm's Law states V = I × R. Voltage (V) equals current (I) in amperes multiplied by resistance (R) in ohms.
1 ampere (A) = 1000 milliamperes (mA). The milli- prefix represents 1/1000 of the base unit.
Capacitance commonly uses microfarads (µF), nanofarads (nF), and picofarads (pF). 1 µF = 1000 nF = 1,000,000 pF.
Inductor values range from nanohenries (nH) in RF circuits to millihenries (mH) in power supplies and henries (H) in audio applications.
