Watt means joule/second, kW (kilowatt) means kilojoule/second, i.e., thousands of joules per second.
A BTU is about 1055 joules. A kilowatt is 1000 joules/second, so it is 3,600,000 joules/hour. Dividing that by 1055 joules gives you the equivalent of about 3400 BTU/hour.
1.5-2.2 litres
They will require 24 bits per second to 30 frames each second.
9.804 meters per second.
9.1x10^2J
Given the wavelength of the photons from above, 3000 nm you just calculate how many joules each photon has and divide that into 100 joules per second.
"59.4 watts" means "59.4 joules every second"
It is approx 3.82*10^26 Joules.
Watts means joules per second. The device uses 1190 joules of energy every second; most of that will be converted to heat. It is best to use SI units most of the time; in this case, joules rather than calories for energy. However, if you want to convert that, 1 calorie = 4.184 joules; thus, you can divide the number of joules by 4.184 to convert it to calories.
1000
Every second a 150 Watt bulb converts 150 Joules from electricity into heat and light. The number of Watts tells you how many Joules pass per second.
10,000 joules per second.
watt (w) means joules per second. kW (kilowatts) means thousands of joules per second. Multiply that by 3600 to get the joules used per hour.
A joule is a joule, whether it be electrical energy or light energy - although commonly, lamps are not 100% efficient.On the other hand, you can't convert joules directly to watts. Watts means joules per second (joules / second), or equivalently, joules is watts times seconds.A joule is a joule, whether it be electrical energy or light energy - although commonly, lamps are not 100% efficient.On the other hand, you can't convert joules directly to watts.

A BTU is about 1055 joules. A kilowatt is 1000 joules/second, so it is 3,600,000 joules/hour. Dividing that by 1055 joules gives you the equivalent of about 3400 BTU/hour.
56 kilo joules = 56,000 joules
