there is 5 lumen per hour in 1 joule
A joule is a derived unit of energy and as such cannot be converted into fps without further information.
About 5.6 miles per hour.
1,609.344 meters per hour.
No. 1 watt = 1 joule per second 1 watt-second = 1 joule 1 kilo-joule = 1,000 joules
There are 238.18 Km/h in 148 miles per hour.
1 lumen = 1 candela per steradian.1 candela = 1/683 watts per steradians (assuming 540nm light wavelength).Assuming that the light is collected from a single steradian:1 Lumen = 1 Candela -> = 1/683 Watt -> Watt = 683 Lumens1 Joule = 1 Watt per Second -> Watt = Joule/SecondHence:683 Lumen = 1 Joule/SecondUnder the above assumptions1 Lumen = 1/683 Joule/Second
There are 1000 milliwatts per lumen.
This conversion would be easy, IF there were a way to convert hours to grams.Unfortunately .....
1 kWh = 1,000 watt-hour1 watt = 1 joule per second1 hour = 3,600 seconds(1,000 watt-hour) = (1,000 joule/second) x (3,600 second/hour) = 3,600,000 joules
If you refer to the energy cost, that doesn't make sense. Lumen means how bright something is - the actual cost will depend on how long you keep a bulb on; in other words, you would get dollars per kilo-lumen per hour, for example - not just dollars per kilo-lumen.
kWh, kilo Watts per hour
in electronics, there is a term of Watt Hours used in power bills and things. watts itself is a unit derived by 1 joule per second. in order to get watt hours (which is just 1 joule per hour) you multiply your watts (joule/second) by 360 (60 seconds in a minute multiplied by 60 minutes in an hour). that will then give you units of joules/hour
One joule per second equates to:One watt or,0.00134 electric horsepower or,3.412 BTUs per hour.
1 cal/day*0.003968321 Btu/cal *1day/24hr = 0.003968321/24 = 0.000165347 Btu/hr
1 kilowatt = 1,000 watts1 watt = 1 joule per second1 hour = 3,600 seconds(1,500 kilowatt-hour) x (1,000 watt / kilowatt) x (1 joule / watt-second) x (3,600 second / hour) =(1,500 x 1,000 x 3,600) x (kilowatt - hour - watt - joule- second) / (kilowatt - watt - second - hour)= 5,400,000,000 joules
Watt is a unit of power, not a unit of energy. Joule is the SI unit for energy; Watt means Joule/second. So, the "per time unit" is already implied. Saying "watt per second" or "watt per hour" would be completely wrong. The power is simply "900 Watt".
10,000 joules per second.
