Space between value and unit

[arnitkun]

pretty-ms does not put a space between numbers and units unless the verbose option is enabled.

However the standard as per wikipedia:

"The International System of Units (SI) recommends inserting a space between a number and a unit of measurement units and between units in compound units, but never between a prefix and a base unit.

5.0 cm not 5.0cm or 5.0 c m
45 kg not 45kg or 45 k g...

The only exception to this rule in the SI the symbolic notation of angles: degree (e.g. 30°), minute of arc (e.g. 22′), and second of arc (e.g. 8″)."

Why does pretty-ms deviate from the standard? Or am I missing something?
I understand that it is very possible to change the result string in the code itself. I just wanted to know.

You are the first to bring this up. It's mostly for stylistic and readability reasons. Also, the name of this package is pretty-ms, not si-correct-ms 😛.

5h 1m 45s
5 h 1 m 45 s

The second one is much less readable.

You could argue that it should have two spaces between components then, but that doesn't look very good either:

5 h  1 m  45 s

Apple doesn't use space between the unit either when showing abbreviated time on iOS/macOS either.

Closing this as I don't intend to change it or add an option to change it.

I was facing the same issue. Here’s a workaround to add a space between value and unit:

prettyMs(value).replace(/(\d+)(\D+)/, '$1 $2')
