+# Humane Units [](https://travis-ci.org/dustin/go-humanize) [](https://godoc.org/github.com/dustin/go-humanize)
+
+Just a few functions for helping humanize times and sizes.
+
+`go get` it as `github.com/dustin/go-humanize`, import it as
+`"github.com/dustin/go-humanize"`, use it as `humanize`.
+
+See [godoc](https://godoc.org/github.com/dustin/go-humanize) for
+complete documentation.
+
+## Sizes
+
+This lets you take numbers like `82854982` and convert them to useful
+strings like, `83 MB` or `79 MiB` (whichever you prefer).
+
+Example:
+
+```go
+fmt.Printf("That file is %s.", humanize.Bytes(82854982)) // That file is 83 MB.
+```
+
+## Times
+
+This lets you take a `time.Time` and spit it out in relative terms.
+For example, `12 seconds ago` or `3 days from now`.
+
+Example:
+
+```go
+fmt.Printf("This was touched %s.", humanize.Time(someTimeInstance)) // This was touched 7 hours ago.
+```
+
+Thanks to Kyle Lemons for the time implementation from an IRC
+conversation one day. It's pretty neat.
+
+## Ordinals
+
+From a [mailing list discussion][odisc] where a user wanted to be able
+to label ordinals.
+
+ 0 -> 0th
+ 1 -> 1st
+ 2 -> 2nd
+ 3 -> 3rd
+ 4 -> 4th
+ [...]
+
+Example:
+
+```go
+fmt.Printf("You're my %s best friend.", humanize.Ordinal(193)) // You are my 193rd best friend.
+```
+
+## Commas
+
+Want to shove commas into numbers? Be my guest.
+
+ 0 -> 0
+ 100 -> 100
+ 1000 -> 1,000
+ 1000000000 -> 1,000,000,000
+ -100000 -> -100,000
+
+Example:
+
+```go
+fmt.Printf("You owe $%s.\n", humanize.Comma(6582491)) // You owe $6,582,491.
+```
+
+## Ftoa
+
+Nicer float64 formatter that removes trailing zeros.
+
+```go
+fmt.Printf("%f", 2.24) // 2.240000
+fmt.Printf("%s", humanize.Ftoa(2.24)) // 2.24
+fmt.Printf("%f", 2.0) // 2.000000
+fmt.Printf("%s", humanize.Ftoa(2.0)) // 2
+```
+
+## SI notation
+
+Format numbers with [SI notation][sinotation].
+
+Example:
+
+```go
+humanize.SI(0.00000000223, "M") // 2.23 nM
+```
+
+## English-specific functions
+
+The following functions are in the `humanize/english` subpackage.
+
+### Plurals
+
+Simple English pluralization
+
+```go
+english.PluralWord(1, "object", "") // object
+english.PluralWord(42, "object", "") // objects
+english.PluralWord(2, "bus", "") // buses
+english.PluralWord(99, "locus", "loci") // loci
+
+english.Plural(1, "object", "") // 1 object
+english.Plural(42, "object", "") // 42 objects
+english.Plural(2, "bus", "") // 2 buses
+english.Plural(99, "locus", "loci") // 99 loci
+```
+
+### Word series
+
+Format comma-separated words lists with conjuctions:
+
+```go
+english.WordSeries([]string{"foo"}, "and") // foo
+english.WordSeries([]string{"foo", "bar"}, "and") // foo and bar
+english.WordSeries([]string{"foo", "bar", "baz"}, "and") // foo, bar and baz
+
+english.OxfordWordSeries([]string{"foo", "bar", "baz"}, "and") // foo, bar, and baz
+```
