But the calories listed on your can of soda are actually kilocalories—each one equal to 1, 000 of the “small calories” that chemists use to measure energy.

但是标在罐装苏打水上的卡路里实际上是千卡，每千卡等于1000卡，这里更小的单位“卡”就是化学家测量能量时用到的。

So when your soda pop says it has 150 food Calories—you'll notice it's written with a capital C—that's the same as 150, 000 small calories—with a little c.

所以如果苏打上写着含有150食物卡路里，你就要注意了，这是用大写的C标明的，这就意味着它等于用小写c标明的150000小卡。
