Reference

How density conversion works

Density is mass divided by volume. Values for actual materials vary with temperature, pressure, composition, and porosity; this tool only converts units, not substance properties.

Values are converted to kilogram per cubic meter first, then from that reference into the requested unit. Keeping a single documented reference reduces inconsistent pair-by-pair constants.

Accuracy note: Unit factors are exact where underlying mass and length definitions are exact.
