Struct measurements::mass::Mass

pub struct Mass { /* fields omitted */ }

The Mass struct can be used to deal with mass in a common way. Metric, avoirdupois imperial and troy imperial units are supported.

#Example

use measurements::Mass;

let metric_ton = Mass::from_metric_tons(1.0);
let united_states_tons = metric_ton.as_short_tons();
let united_states_pounds = metric_ton.as_pounds();
println!(
    "One metric ton is {} U.S. tons - that's {} pounds!",
    united_states_tons, united_states_pounds);
