SI Ohm Prefix Converter (mΩ, Ω, kΩ, MΩ, GΩ)

to = from × 10^(fromExp − toExp) on ohms.

Through-hole resistors print k and M. Shunts print milliohms. Insulation testers print gigaohms. Same ohm. Color bands still need a decoder; this page only moves the decimal.

How this calculator works

Through-hole resistors print k and M. Shunts print milliohms. Insulation testers print gigaohms. Same ohm. Color bands still need a decoder; this page only moves the decimal. to = from × 10^(fromExp − toExp) on ohms. Example: 10 kΩ → 10,000 Ω → 0.01 MΩ. A 50 mΩ shunt is 0.05 Ω.

to = from × 10^(fromExp − toExp) on ohms.

Example: 10 kΩ → 10,000 Ω → 0.01 MΩ. A 50 mΩ shunt is 0.05 Ω.

When to use this SI Ohm Prefix

Common use cases

  • Through-hole resistors print k and M. Shunts print milliohms. Insulation testers print gigaohms. Same ohm. Color bands still need a decoder; this page only moves the decimal.
  • Sanity-check with this case: 10 kΩ → 10,000 Ω → 0.01 MΩ. A 50 mΩ shunt is 0.05 Ω.
  • The relationship is: to = from × 10^(fromExp − toExp) on ohms.

Localized examples

What you get

  • Fields: From prefix
  • to = from × 10^(fromExp − toExp) on ohms.
  • Example on the page: 10 kΩ → 10,000 Ω → 0.01 MΩ. A 50 mΩ shunt is 0.05 Ω.

How to Convert SI Ohm Prefix Step-by-Step

  1. 1Enter From prefix. Use the values you have, not a catalog average, unless that is all you know.
  2. 2to = from × 10^(fromExp − toExp) on ohms.
  3. 3Worked case: 10 kΩ → 10,000 Ω → 0.01 MΩ. A 50 mΩ shunt is 0.05 Ω.
  4. 4Check which dictionary the other person is using — US or UK, decimal or 1,024 — then trust the number.

Governing formula

to = from × 10^(fromExp − toExp) on ohms.

10 kΩ → 10,000 Ω → 0.01 MΩ. A 50 mΩ shunt is 0.05 Ω.

Example: set From prefix = 10, then read the result.

Very usable on mobile. Would love a save/export option later, but the math feels solid.

Simple inputs, clear outputs. This replaced three bookmarks I used to juggle.
