To answer this question the wattage of the block heater must be stated. Amps = Watts/Volts.
40 amps
8,33 Amps

The electric heater will have power rated in Watts. The Amps it will draw depends on the voltage system you are using. Can be calculated by formula I (Amps) = P / V In the USA with 110V system a 2400W heater will draw 2400 Watts / 110 Volts = 21.8 Amps In Australia with a 230 V system a 2400W heater will draw 2400 Watts / 230 Volts = 10.4 Amps
The formula you are looking for is I = W/E.

To answer this question the voltage of the heater must be given. I = W/E.
Find the block heater and look for the nameplate on it. It will be in watts. Use the following equation to find the amperage that it draws. Amps = Watts/Volts. The voltage to use for the truck will be 12 volts.

It uses 1150 watts, or 10 amps.
The electric heater will have power rated in Watts. The Amps it will draw depends on the voltage system you are using. Can be calculated by formula I (Amps) = P / V In the USA with 110V system a 2400W heater will draw 2400 Watts / 110 Volts = 21.8 Amps In Australia with a 230 V system a 2400W heater will draw 2400 Watts / 230 Volts = 10.4 Amps
The formula you are looking for is I = W/E.
9000 BTU/hour is equivalent to 2300 watts so the heater will draw 10 amps on 230 volts.
For a single phase circuit, the equation you are looking for is I = W/E. Amps = Watts/Volts.
draw 0.104 amps
The heater should have a wattage rating (very few list amps). Calculate the amps using the wattage and voltage. Amps = Watts/Volts(480).
