Heat Ratings. The output of a radiator is measured in British Thermal Units (BTU.s) per hour. (So is air-conditioning, come to that!) 3000 BTU is roughly equivalent to a 1 kilowatt bar heater, just to give you some idea.

If you live in a place where it gets cold often, or during the winter time, you will get better results using 5w30.Otherwise 10w30 oil is good enough, i usually use 5w30 all year round.ating Newest Oldest.

Best Answer: A kilowatt is 1000 watts. A kilowatt hour is 1000 watt-hrs. If the appliance uses 45 Watts, you divide by 1000 to convert it into kilowatts and then multiply that by the number of hours (giving you kilowatt hours) . So 45 W * 3.5 hrs /1000 = 0.1575 KWH.
