I am writing my Master Thesis memory and I have come up with a doubt, how should I write 1 megahertz: 1MHz (without space) or 1 MHz (with space)?

I searched on the internet, on papers and books, and I have found it written in both ways. Which should I use?


The most secure way is to do it with siunitx: the macro \SI{1}{\MHz} will typeset it correctly, with a thin space between the number and the unit, and no space inside the unit.
