+# Print Milliseconds In Human-Readable Format
+
+I ran a command in a program. It doesn't really matter what command or program.
+What does matter is that it took a long time and when it finished, it told me
+how long it took, but in milliseconds.
+
+```
+835953ms
+```
+
+Typically, when I see a timing number like this, I open Alfred and do some
+quick math (`N / 1000 / 60 / 60` or something like that).
+
+There is an easier way, using the
+[`pretty-ms-cli`](https://github.com/sindresorhus/pretty-ms-cli). This
+purpose-built CLI can be run using something like
+[`npx`](https://www.npmjs.com/package/npx). All I do is hand it the number of
+milliseconds and it prints out how long that is in something that I can
+understand.
+
+```bash
+❯ npx pretty-ms-cli 835953
+13m 56s
+```
