Why is air conditioning often referred to as A/C? Why the slash?

I don't understand why it's A/C, what's the purpose of the slash? Are there other examples of the same usage?

I think it's to make a difference between AC as Air Conditioning and A/C as Air Conditioner. However, in India, we use AC for everything!

So, when you purchase a unit, you may not prefer to say that you bought an AC. Please note that when you turn on/off, both are okay as you can do that for air conditioning and conditioner as well!

However, I'd say there's no major difference left today. AC and A/C both are in practice (at least wherever I've read) and they are interchangeable.

2I don't know, but adding the slash might have something to do with the fact that AC also stands for Alternating Current. – Brian Hitchcock – 2015-06-01T07:19:17.747
