How is tach pronounced?

Every time I'm talking tach with my colleagues I'm struggling to figure out how it is supposed to be pronounced, and cannot find any information about it? 🤔

It is pronounced like 'tack' :)

It comes from the word tachometer, also known as an RPM gauge. This is probably a good thing to add to the FAQ!
