Full API documentation

Explanation

For Ferrous Sulfate Heptahydrate, g/L is the base reference and molar mass is 278.01 g/mol. % w/v -> g/L via the definition: 1% w/v = 1 g per 100 ml = 10 g/l. g/L -> mmol/L via the uses solute molar mass with si milli scaling. Combined factor: 1 % w/v = 35.9699291392 mmol/L. Ferrous Sulfate Heptahydrate keeps one fixed solution-concentration basis, so the snapshot, calculator, common values, and mirror route stay aligned.

Hydrated iron(II) sulfate reference. When molar units are involved, the same molar-mass assumption stays constant rather than switching reference values between blocks.

Method & Solute Basis

Method basis: this conversion runs through grams per liter and uses the molar mass of Ferrous Sulfate Heptahydrate whenever a molar unit is involved.
Solute reference: Ferrous Sulfate Heptahydrate. The page keeps one fixed g/L normalization path for this solute.
Consistency rule: calculator output and table values use the same constants and rounding policy.
