Struct measurements::pressure::Pressure

pub struct Pressure { /* fields omitted */ }

The Pressure struct can be used to deal with presssures in a common way. Common metric and imperial units are supported.

Example

use measurements::Pressure;

let earth = Pressure::from_atmospheres(1.0);
let mbar = earth.as_millibars();
println!("Atmospheric pressure is {} mbar.", mbar);
