Resistance converter
Ω, kΩ, MΩ, mΩ.
1 kilohm = 1,000 ohms
How it’s calculated
Ω = kΩ × 1000
- Multiply the value in kilohms by 1000.
- To go back, divide by 1000 (or multiply by 0.001).
- 1 kΩ = 1,000 Ω · 1 Ω = 0.001 kΩ

Find the conversion factor
By definition 1 kΩ = 1000 Ω. Source: BIPM SI Brochure (9th ed.) (SI prefixes and accepted units); BIPM SI Brochure (9th ed.).
Multiply by the factor written as a fraction
Put kΩ in the denominator so it cancels, leaving Ω.
Calculate (unrounded)
Round the answer
Rounded to 5 significant figures.
Answer: 1000 Ω
1 kΩ in other units
Batch convert kΩ → Ω
Results
- 1 kΩ = 1000 Ω
- 5 kΩ = 5000 Ω
- 10 kΩ = 10000 Ω
- 25 kΩ = 25000 Ω

Frequently asked questions
Which resistance units can I convert?
ohms (Ω), milliohms (mΩ), kilohms (kΩ), megohms (MΩ), gigohms (GΩ).
How accurate are the results?
Every unit is stored with its exact defining factor (NIST SP 811, NIST Handbook 44 or the BIPM SI Brochure). Calculations use double-precision arithmetic and are rounded only for display, to 5 significant figures by default (trailing zeros dropped, so 1 km shows as 1000 m). You can choose Auto (up to 10 digits), fixed decimals or more significant figures, or switch to scientific or engineering notation.
