How to reference carried weight?

So, you can find out how much a container/person/supporter can hold by using the phrase “carrying capacity”. What phrase can you use to tell how much they’re actually holding right now?

Take a look at the Recipe Book examples: inform7.com/learn/man/Rdoc84.html

That’s much more complicated than I meant. I’m not looking to assign weights to each item, rather just to tell how much of the carrying capacity is currently used up.

I figured it out–simple enough. Since each thing held takes up 1 part of the carrying capacity, I just need to reference how many things the player is holding and in the simple default system that gives a number.
So, in my specific case “Instead of taking the pile of paper when the player is holding at least two things or the player is holding the battery:”

Thanks!
