Convert mM to M (and µM)

Real-time unit conversion for molar concentration.

Decimals: 3
1 M = 1000 mM
120 mM = 0.12 M
Result
120 mM
  • mM 120
  • M 0.12

Quick tips

  • Pick the correct liquid preset before converting.
  • For medications, match the exact labeled mg/mL.
  • Use Decimal to control rounding; trailing zeros are trimmed.

How the mg to mL Calculator Works

How many mg in a mL?

It depends on the liquid. For water at room temperature, 1 mL ≈ 1000 mg. For medications, use the product’s mg/mL strength.
