Electrical Resistance Unit Converters
Convert mΩ, Ω, kΩ, MΩ, and GΩ values using exact powers-of-ten prefix scaling.
Scope & Verification
This hub groups related converter families so you can move from the category level to exact routes with one clear basis per page.
- Families are split so exact-factor, profile-based, density-based, and estimate-style pages do not collapse into one generic answer.
- Leaf pages keep calculator, common values, FAQ, and reverse routes aligned to the same assumption.
- Methodology and verification pages document how those assumptions are chosen and checked.
Explanation
Electrical resistance quantifies how strongly a component opposes electric current. The SI unit is the ohm (Ω), defined by the exact relationship Ω = V/A. Prefix scaling is exact: 1 mΩ = 10⁻³ Ω, 1 kΩ = 10³ Ω, 1 MΩ = 10⁶ Ω, and 1 GΩ = 10⁹ Ω. These conversions are purely multiplicative with no additive offsets. Every factor in this hub is derived by reducing units to ohms and then applying exact SI prefix powers. For clarity, resistance conversions are grouped into base-to-prefix, electronics-scale, and high-resistance relationships.
Frequently Asked Questions
How many ohms are in one kilohm?
One kilohm equals exactly 1,000 ohms.
Does converting resistance calculate current?
No. Current also requires voltage and a circuit relationship such as Ohm's law.
Are resistor tolerances included?
No. The pages convert nominal units; component tolerance remains separate.
