========

[![Build Status](https://travis-ci.org/ArtskydJ/bmi-calc.svg)](https://travis-ci.org/ArtskydJ/bmi-calc)

A Body Mass Index calculator.

# example

```js
var calcBmi = require('bmi-calc')

// 154 lbs, 72 in, imperial
console.log( calcBmi(154, 72, true) )
// { value: 20.88, name: 'Normal' }

// 69 kg, 1.62 m, metric
console.log( calcBmi(69, 1.62, false) )
// { value: 26.29, name: 'Overweight' }

// 59 kg, 2 m, metric
console.log( calcBmi(59, 2) )
// { value: 14.75, name: 'Very Severely Underweight' }
```

# api

```js
var calcBmi = require('bmi-calc')
```

# `var bmi = calcBmi(weight, height, [imperial])`

- `weight` is a number in pounds or kilograms
- `height` is a number in inches or meters
- `imperial` is an optional boolean that defaults to `false`.
- If `true`, `weight` is interpreted as pounds, and `height` as inches.
- If `false`, `weight` is interpreted as kilograms, and `height` as meters.

# `bmi`

`bmi` is an object with the following properties:

- `value` is the bmi number, e.g. `21.36`
- `name` is a human-readable string, e.g. `'severely underweight'`

# cli

- Install [node](http://nodejs.org/download).
- Run `npm install -g bmi-calc`
- Run `bmi-calc --pounds 170 --inches 73`. (Except put in your weight and height.)

```
