This is the {{nowrap}} template.

This template prevents word wraps (line breaks) in text and links that contain spaces.

For additional information, see wikipedia.org documentation at [1]. Before you use this template you might want to read up on Wikipedia:Line break handling.

Usage

Lots of text {{nowrap|10 kg (22 lb)}} more text.

It may render like this:

Lots of text 10 kg (22 lb)
more text.

Or like this:

Lots of text
10 kg (22 lb) more text.

But it will not render like this:

Lots of text 10 kg (22
lb) more text.
