how to convert amps into kwh usage

I have a pop machine operating at 120 volts drawing 11 amps, what is my conversion to kWh per hour?

120 V x 11 A = 1320 W or 1.32 kW

In an hour, it will use 1.32 kWh, in two hours, 2.64 kWh

Kilowatt-hours are a unit of energy, the product of kilowatts (power) and hours (run time).

i need to convert 1.2 ampere of usage into kwh...

What is the voltage?
For how many hours of run time.

i need to convert 250 ampere of usage into kwh

Does the number of Phases have an effect on the consumption

covert Kwh/kg to mAh/g

Multiply by 1000, divide by voltage.

kWh/kg is numerically equal to Wh/g
1 W = 1 A x 1 V, so divide by volts to get Ah/g
multiply by 1000 for mAh/g

Hi, I stumbled across this searching Google.
Would I be right in thinking the following based on 3.3 amps, using 240v;
3.3x240=0.792kWh.
Assuming a cost of 0.043 per kWh, then 24 hours usage=0.81?
This seems quite low, so I'm not certain I have the right idea.

Numerically yes. Some minor units issues:
3.3 A x 240 V = 792 W or 0.792 kW, a unit of power.
A kilowatt for an hour, kWh, is a unit of energy.
0.792 kW x 24 h = 19 kWh (assuming it runs the full 24 h and current draw is constant)
19 kWh x $0.043/kWh = $0.817, call it $0.82
