Calculators

Formula-transparent · Free to use

Use focused chemistry calculators for concentration, solution preparation and molecular formulas. Each tool shows its equation, unit assumptions and scope so you can verify the result.

C₁V₁

Dilution Calculator

Calculate the stock volume required for a label-directed target concentration and final volume.

Open calculator → ppm

PPM Converter

Convert ppm, ppb, percent, mg/L and g/L with an explicit solution-density input.

Open converter → mol/L

Molarity Calculator

Calculate molarity from moles or mass, or find the theoretical mass for a target molarity.

Open calculator → Mr

Molar Mass Calculator

Parse chemical formulas, parentheses and hydrates to calculate molar mass and mass percentages.

What is the mass of one mole?	Molar Mass Calculator

Calculation is not authorization. These tools do not decide whether chemicals may be mixed, which concentration should be used, or whether a product is suitable for a surface. Follow the controlling label, method or protocol.

How ChemicaLife handles calculations

Inputs are normalized to consistent units before the formula is applied. Results include the normalized values or element breakdown needed to reproduce the calculation. Safety-related calculators use hard stops where the requested calculation falls outside their stated scope.

For chemical combinations, use Mix Check. For contact between a chemical and a surface or container, use Material Compatibility.
