pub struct Mass;
Expand description
Measure of mass.
Mass is a “base quantity”, with units such as kg
and lb
.
Example
use mag::mass::{kg, lb};
let a = 2.5 * kg;
assert_eq!(a.to_string(), "2.5 kg");
assert_eq!(a + 4.5 * kg, 7 * kg);
assert_eq!(a.to(), 5.511556554621939 * lb);
Example: Solar Mass Units
use mag::{declare_unit, mass::kg, quan::Mass};
declare_unit!(M, "M☉", Mass, 1.988_47e33,);
let sun = 1 * M;
assert_eq!(sun.to_string(), "1 M☉");
assert_eq!(sun.to(), 1.988_47e30 * kg);
