Kilohms to Ohms

1 kilohm = 1,000 ohms · 1 Ω = 0.001 kΩ

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

  1. 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.).

  2. Multiply by the factor written as a fraction

    Put kΩ in the denominator so it cancels, leaving Ω.

  3. Calculate (unrounded)

  4. Round the answer

    Rounded to 5 significant figures.

Answer: 1000 Ω
