9000 BTU/hour is equivalent to 2300 watts so the heater will draw 10 amps on 230 volts.
9000 watts is zero amps. Amps are the product of amps times volts. Without a voltage stated an answer can not be given. I = W/E, Amps = Watts/Volts.
A btu is a measure of energy, but 18,000 btu per hour is a power of 5.22 kW, which is 5220/220 amps, 24 amps.
The Amps means the volume of flow of electricity. The Amps depends on its BTU (British Thermal Unit). BTU is the unit to measure the energy that is consumed to perform some Air Conditioner. 12000 BTU Air conditioners uses 5 to 6 Amps. 18000 BTU Air conditioners uses 9 to 10 Amps. 12000 BTU air conditioners also called 1 Ton AIR CONDITIONER and 18000 BTU Air conditioners are called 1.5 Ton and so on. The 2 Ton or 24000 BTU Air conditioners use 15 Amps to work.
at 230v it will use 5 to 6 amps
Divide the wattage rating on the tag by the voltage it uses and that will give you the amperage.
4400 watts converts to how many amps
25
8000 BTU =2344.66 watts 1 watt = 3.412
First you need to find out how many amps the heater draws. Then use this formula: Volts (220) X Amps = Watts Then take: Watts x 3.41214 = Btu/hr
10.92 Amp
