Measuring rice

How come a cup of rice is a smaller measurment than a cup of anything else? Just some old tradition?

rice will expand after cooking

Why is it smaller? I’d never heard that. I always use my standard (dry measure) cup for ladling out rice. Should I use something different?

I think he’s talking about the little cup that comes with a rice cooker. That’s actually calibrated to the markings on the side of the pot that you use to measure the water.
