Scientists use joules to measure energy.

科学家用焦耳来测量能量。

This battery can store 500 joules of energy.

这个电池可以储存500焦耳的能量。

This light bulb consumes 60 joules of energy per second.

这个灯泡每秒消耗60焦耳的能量。

At that time it wasn't called joules yet.

不过那时候还不叫焦耳。

This is 10 to the minus 18 joules for this one atom.

对单个原子，就是10的负18次方焦耳。

Now you can see 2.18 times 10 to the minus 18 joules can be 13.6 eV.

你可以看到,2。18乘10到负18焦耳,得到13。6电子伏特。

For instance, an LED desk lamp's 6 Watt bulb transfers 6 Joules of light energy per second.

比如，一个LED灯的6瓦灯泡，每秒转移6焦耳的光能。

And if you do so, you will end up with 1.312 mega joules per mole for this quantity K.

这样做之后，对于K常量你就能得到2,1。312百万焦耳每摩尔。

On a regular sleigh, this would require the reindeer to endure 14.3 quintillion joules of heat.

如果是普通的雪橇，那拉雪橇的驯鹿就要面临14.3个百万三次方焦耳的热量。

So, keep in mind that one milliwatt is just the same as saying 1 times 10 to the -3 joules per second.

所以，请记住1毫瓦,和1乘以10的-3次方焦耳每秒,的说法是等同的。
