Convert a density into every unit at once
Enter one value and a unit — kilograms per cubic meter, grams per cubic centimeter, kilograms per liter, pounds per cubic foot, pounds per cubic inch, or pounds per US gallon — and read it back in every unit at once. Each input is reduced to a canonical value in kg/m³ using exact factors (1 g/cm³ = 1000 kg/m³, water), then every output is derived from that base. Note that g/cm³ and kg/L are numerically equal. Decimals are supported, but a density cannot be negative.
