+# [postcss][postcss]-convert-values
+
+> Convert values with PostCSS (e.g. ms -> s)
+
+## Install
+
+With [npm](https://npmjs.org/package/postcss-convert-values) do:
+
+```
+npm install postcss-convert-values --save
+```
+
+## Example
+
+This plugin reduces CSS size by converting values to use different units
+where possible; for example, `500ms` can be represented as `.5s`. You can
+read more about these units in [this article][csstricks].
+
+### Input
+
+```css
+h1 {
+    font-size: 16px;
+    width: 0em
+}
+```
+
+### Output
+
+```css
+h1 {
+    font-size: 1pc;
+    width: 0
+}
+```
+
+Note that this plugin only covers conversions for duration and absolute length
+values. For color conversions, use [postcss-colormin][colormin].
+
+## API
+
+### convertValues([options])
+
+#### options
+
+##### length
+
+Type: `boolean`
+Default: `true`
+
+Pass `false` to disable conversion from `px` to other absolute length units,
+such as `pc` & `pt` & vice versa.
+
+##### time
+
+Type: `boolean`
+Default: `true`
+
+Pass `false` to disable conversion from `ms` to `s` & vice versa.
+
+##### angle
+
+Type: `boolean`
+Default: `true`
+
+Pass `false` to disable conversion from `deg` to `turn` & vice versa.
+
+##### precision
+
+Type: `boolean|number`
+Default: `false`
+
+Specify any numeric value here to round `px` values to that many decimal places;
+for example, using `{precision: 2}` will round `6.66667px` to `6.67px`, and
+`{precision: 0}` will round it to `7px`. Passing `false` (the default) will
+leave these values as is.
+
+It is recommended for most use cases to set this option to `2`.
+
+
+## Usage
+
+See the [PostCSS documentation](https://github.com/postcss/postcss#usage) for
+examples for your environment.
