Hz means Hertz which is a measure of frequency. It was once just referred to as cycles per second. In the USA 60 Hz is the normal frequency for AC in a business or residence. It has nothing to do with the amperage per se.
There is no fixed connection between frequency (Hertz) and voltage, you can have 60 Hz at any voltage.

If your device uses 900 Watts at 7.5 Amps, then it requires 120 volts. If you want to use it where the supplied current is 220 volts, then you'll need a transformer - but only if the device can operate on 50 Hz. Most places that use 220 Volts supply it at 50 Hz. If your device says it can operate on 50 Hz you can use a transformer.
All North American utility suppliers are set up for 60 Hz. As such, all breakers are designed for 60 Hz operation. Although European electricity is 50 Hz, North American breakers would no doubt function well. It is highly recommended that you employ the services of a qualified electrician for installation or modification of any electrical service.
The formula you are looking for is W = Amps x Volts.
i went onto whirlpool's site and checked a basic electric range for some specs.here's a cut and paste from there:Electrical Requirements15 Amps. 60 Hz. 120 V.

There is no inherent disadvantage of 50 Hz compared with 60 Hz, bearing in mind that systems that run at 50 Hz are designed to run at 50 Hz.
the maximum rating is 60 hz . it is work in50hz
