Even though you seemingly did the same thing, but volumetric measurements, they're just not very reliable.

即使你看起来做了同样的事情，但用体积测量不是很可靠。

Now the problem I have with scoops or cups or tablespoons or teaspoons, or all of that sort of stuff is that they're volumetric measurements.

我用勺子，杯子，大汤匙，茶匙，或者所有这类东西时遇到的问题是它们是体积测量的。
