It's ton, not tone. 1 ton of air conditioning is equal to 12,500 BTU/hour.

I'm not going to do your job for you, so you'll have to find an on-line servant.

Can you Google?

I thought maybe since they are 60 Hz systems, the perfect tone would therefore be 60 Hz.

Hmmmm?

Well, only at sea level. See, Hz goes up with pressure. That's why Europe runs at 50 Hz. They are closer to sea level.

North America, being higher, runs at 60 Hz.

So, at 300PSI the tone would not be 60 Hz but 1285.7142 Hz.
