Joules is a unit of energy; watts is a unit of power. You can't just convert it. The relationship between the two is:
power = energy / time
in units:
watts = joules / second

If the light bulb from number 10 radiates 100 watts times 100 joules per second of photons. How many photons per second are radiated?
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.
How do you convert Joules per sq cm to Joules?

Convert 9.0eV into joules?
One electron volt (eV) is equal to 1.60218 E (-19) joules. Therefore, 9.0 eV is equal to 1.44196 E (-18) joules.
How do you convert 60.5 joules to calories?
One joule is about 0.24 calories. So: 60.5 joules x 0.24 = 14.52 calories.
How many kilocaclories of heat does the operation of a 1190 watt hair dryer produces each second?
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.

How do you convert from killi joules to joules?
To convert from kilo joules to joules you have divide by 1000 as 1 kilo joule is equal to 1000 joules. E.g. 2 kilo joules equals 2000 joules.
How do you convert kilojoules to joules?
To convert from kilojoules to joules you have divide by 1000. meaning 1 kilo joule is equal to 1000 joules.

How do you convert Joules To fahrenheit?
You cannot convert Joules to Fahrenheit. They are two different kinds of measurements. Fahrenheit measures temperature and Joules measures energy.
How do you Convert 3 calories to joules?
4.18400 joules = 1 calorie, so 12.552 joules = 3 calories
How do you you convert cal to joules?
1 calorie = 4.1858 joules 1 joule = 0.2389029576186153 calories As an example, convert 5 calories to joules. 1 calorie = 4.1858 joules, therefore 5 calories = 4.1858 x 5 joules = 20.929 joules. So when converting calories to joules, multiply the number of calories by 4.1858 to give you the number of joules.
Why is there no substance that convert visible light to UV?
UV photons have more energy (less wavelength, higher frequency) than visible light photons. It is possible to convert photons to ones with less enery, but not the opposite.
Can you Convert 5.42 calories to joules?
Yes. 5.42 calories equates to 22.692456 joules.
How do you convert joules to cm?
It isn't possible. Joules is the measure of energy and cm is a measure of distance.
How do you convert 1997436.144 Kilojoule to KiloWAtt?
You can't convert from Joules to Watts because Joules is a measure of total energy, and Watts measure energy per second.
Convert 355 nanometers to Joules?
It's impossible. Nanometers are units of distance and Joules are units of energy.
