Density changes with temperature — water is 1 g/cm3 near 4 degrees Celsius and slightly less when warm. The conversions are exact; the material values you start from are the approximation.

Convert kilograms per cubic metre to grams per cubic centimetre, kilograms per litre and pounds per cubic foot — for liquids, materials and shipping maths.
Water has a density of 1 g/cm3, which is 1,000 kg/m3 or 62.43 lb/ft3. Ice, at about 0.917 g/cm3, is lighter — which is why it floats.
Result = input × source-unit factor ÷ destination-unit factor. All factors are relative to the same base unit; intermediate values are not rounded.
kg/m³, g/cm³, kg/L, g/mL, lb/ft³, lb/gal (US). Read the labels carefully: regional or decimal/binary variants are separate choices.
Neither — but steel, at about 7,850 kg/m3, packs that kilogram into a far smaller volume. Density compares mass per unit of volume, not total weight.
