To calculate the cost per hour for a 400W heater, you need to know the electricity rate per kilowatt-hour (kWh) charged by your utility company. For example, if the rate is $0.12 per kWh, a 400W heater would use 0.4 kWh per hour (since 400W = 0.4 kW). Multiplying 0.4 kWh by $0.12 gives you a cost of $0.048 per hour to run the 400W heater.
To convert from kilowatts (kW) to British Thermal Units (BTU) per hour, multiply by 3412. Therefore, a 5kW heater would produce 5 * 3412 = 17060 BTU per hour.
To convert kilowatts (kW) to British Thermal Units (BTU), you can use the conversion factor 1 kW = 3412 BTU/hr. Therefore, a 5 kW heater would produce 5 kW * 3412 BTU/hr = 17060 BTU per hour.
BTU is a measure of energy, while a kilowatt is a measure of power. Energy is power times time. Energy: measured in BTU or kilowatt-hours Power: measured in BTU/hour or kilowatts. 100,000 BTU equals about 29 kWh so a 1 kW heater produces about 3400 BTU per hour.
To convert 5 kW to BTU/hr, multiply by 3412 (1 kW = 3412 BTU/hr). Therefore, a 5 kW heater will produce 17,060 BTUs (5 kW * 3412 BTU/hr) if operated for 1 hour.
Anything up to 10 miles, zero if driven in circles.
Well 1 KWh is "1000 watts per hour". So if you have 400w per hour take400watts per hour divided by 1000 and it shows that you get "0.4KWh".AnswerThere is no such thing as a 'kilowatt per hour', which is why the unit of measurement is a 'kilowatt hour', and NOT a 'kilowatt per hour'!.To determine the number of kilowatt hours of energy consumed by the lamp, multiply its power, expressed in kilowatts, by the length of time it is in use. For your example, the answer is 0.4 kWh.
50$ an hour
Your term "hydro" is another term for kilowatt hours. So to answer your question a 4800 watt heater on for an hour would consume 4.8 kilowatt/hours. To take it further if you knew what you pay for a kilowatt hour in your area, multiply it by 4.8 and you could see how much it costs you to operate the heater. An example if you pay .11 cents a kilowatt hour, the price would be .528 or 53 cents an hour.
To convert from kilowatts (kW) to British Thermal Units (BTU) per hour, multiply by 3412. Therefore, a 5kW heater would produce 5 * 3412 = 17060 BTU per hour.
Depends on the size of the pc.. but. assuming a 400W psu, and a 30W lcd screen. 215Wh would be the amount of power it uses or 0.215 kWh or 774 kJ
1100 an hour
To calculate the cost of running a 2 kilowatt convector heater per hour, you need to know the electricity rate charged by your utility company. Let's assume the rate is $0.12 per kilowatt-hour. In this case, running a 2 kilowatt convector heater for an hour would cost $0.24 ($0.12 x 2).
The first hour rating of this water heater model is the amount of hot water it can provide in the first hour of use.
Depends on the BTUs of the heater.
A 18,000 BTU heater uses approximately 0.157 therms per hour. This can vary slightly depending on the efficiency of the heater and the specific model.
You would make about $26.00 an hour
starting pay would be 13 an hour.
