Electrical Resistance Conversion Formulas

Use the following formulas to convert between ohms, kiloohms, and megohms.

kΩ to Ohms
Ω = kΩ × 1,000
Ohms to kΩ
kΩ = Ω ÷ 1,000
MΩ to kΩ
kΩ = MΩ × 1,000
Example: Convert 4.7 Kiloohms (kΩ) to Ohms (Ω)
Ω = 4.7 × 1,000
Ω = 4,700 Ω

By Ohm's Law (R = V / I), 1 Ohm is the electrical resistance across which 1 Volt produces 1 Ampere of current.
