Molarity to Normality Calculator
This molarity to normality calculator converts molar concentration (M) to normal concentration (N) using the equivalence factor (n-factor). Enter molarity and the number of reactive units (H⁺, OH⁻, or electrons) to get normality instantly.
Molarity to Normality Calculator
Molarity × n-Factor = Normality
N = M × n-factor What is Molarity to Normality?
Normality (N) is molarity multiplied by the number of equivalents per mole, called the n-factor. For acids, n = number of H⁺ ions released. For bases, n = number of OH⁻ ions. For redox, n = electrons transferred.
Examples: H₂SO₄ has n-factor = 2 (releases 2 H⁺), so 1 M H₂SO₄ = 2 N. NaOH has n-factor = 1, so 1 M NaOH = 1 N. H₃PO₄ has n-factor = 3, so 1 M = 3 N.
Normality is used primarily in titration calculations and equivalence-point determinations. Modern chemistry prefers molarity, but normality remains common in analytical chemistry and water treatment.

Molarity to Normality Calculator Examples
The examples below show how to use the molarity to normality calculator in practice.
Example 1: What is the normality of 1 M H₂SO₄? H₂SO₄ donates 2 H⁺ ions, so n-factor = 2. Normality = 1 × 2 = 2 N.
Example 2: Using the formula: molarity = moles ÷ volume, compute the result and verify with the calculator above.
Example 3: Enter your own values into the calculator to see personalized step-by-step results.

FAQs
How do you convert molarity to normality?
Normality = Molarity × n-factor. The n-factor is the number of H⁺ (for acids) or OH⁻ (for bases) ions per formula unit, or electrons transferred in redox.
What is the normality of 1 M H₂SO₄?
H₂SO₄ donates 2 H⁺ ions, so n-factor = 2. Normality = 1 × 2 = 2 N.
When is normality used instead of molarity?
Normality is used in titration and equivalence calculations. Molarity is preferred in modern chemistry; normality is legacy but still common in analytical chemistry.
What units does the Molarity to Normality Calculator support?
The molarity to normality calculator supports mass units (g, mg, µg, kg), volume units (L, mL, µL, gal), molar mass (g/mol, kg/mol), and molarity units (M, mM, µM, nM, pM, fM, aM).
