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
This conversion would be easy, IF there were a way to convert hours to grams.Unfortunately .....
There are 1000 milliwatts per lumen.
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".
Watts are units of power. Joules are units of energy. They are not the same. One watt is one joule per second.
