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 Lumens
1 Joule = 1 Watt per Second -> Watt = Joule/Second
Hence:
683 Lumen = 1 Joule/Second
Under the above assumptions1 Lumen = 1/683 Joule/Second

How many joule equals 1 MW energy?
1 watt/second equal to 1 Joule
How many Wh is in 1 joule?
0.00027777777777778 Wh1 Wh = 3600 Joule
How many mega joules are there in a joule?
1 mega-anything = 1 million of them. 1 joule = 0.000001 megajoule
How many volts of electric in one jewel?
If you actually mean the unit of energy, Joule, then 1 Volt = 1 Joule/1 Coulomb, or 1 Joule = 1 Volt * 1 Coulomb
How many joules are in a newton?
1 Newton is 1 joule/meter.
How many lumen per hour are in 1 joule?
there is 5 lumen per hour in 1 joule
How many calories are there in 1 joule?
1 joule = 0.2388 calories.
How many ergs equals i joule?

1 watt/second equal to 1 Joule
1 joule equals how many eV?
1 joule = 6.215 x 1018 eV
How many calories equals how many joule?
1 calorie = 4.184 joules So, 200calories * (4.184joules/1calorie) = 200*4.184 joules= 836.8 joules Since the category of this question is nutrition, I will point out that "calories" on food are actually "Calories". Notice the capital "c". It makes a difference. "Big c" calories are actually calories * 1000! A 100 Calorie snack isn't 100*4.184 = 418.4 Joules, it is 100,000 *4.184 = 418,400 Joules!
How many erg make a joule?
1 joule = 10 million ergs
How many calories are equal to 1 joule?
One joule is 0.239 calories.
How many mega joules are there in a joule?
1 mega-anything = 1 million of them. 1 joule = 0.000001 megajoule
How many calories in a joule?
We know that 1 joule is the same as 0.239 calories. (Also, 1 calorie is 4.184 joules.)
