MG/ML to Molarity Calculator

Convert concentration from mg/mL to molarity (M, mM, μM)

Formula

Molarity (M) = (Concentration in mg/mL) / (Molecular Weight in g/mol)

Note: 1 mg/mL = 1 g/L

M = (mg/mL) / (g/mol) = (g/L) / (g/mol) = mol/L

Concentration (mg/mL)

Also known as: mg per milliliter or milligrams per milliliter

Molecular Weight (g/mol)

Also known as molar mass (g/mol or g·mol⁻¹)

About MG/ML to Molarity Conversion

Converting mg/mL to molarity is commonly needed in biochemistry and pharmacology. The key insight is that 1 mg/mL equals 1 g/L, which simplifies the calculation. Simply divide the concentration by the molar mass to get molarity.

Quick Reference:

• 1 M = 1000 mM (millimolar)
• 1 M = 1,000,000 μM (micromolar)
• 1 mg/mL = 1 g/L
