README
[Mag] is a library for dealing with physical quantities and units.
Quantities are created by multiplying scalar values by a unit type. These units
are named after common abbreviations:
```rust
use mag::{length::{ft, m, mi}, time::{h, s}};
let a = 1.0 * ft;
assert_eq!(a.to_string(), "1 ft");
let b = a.to::();
assert_eq!(b.to_string(), "0.3048 m");
let c = 30 * s;
assert_eq!(c.to_string(), "30 s");
let d = 60.0 / s;
assert_eq!(d.to_string(), "60 ㎐");
let e = 55.0 * mi / h;
assert_eq!(e.to_string(), "55 mi/h");
```
## Highlights
* Easy to understand and use
* Performs conversions between units (SI, imperial)
* Units are not discarded when creating quantities
* Fast compile time
* No external dependencies
## Alternative
If mag doesn't fit your needs, you could try the [uom] crate, which has many
more features.
