It's also a lot easier to multiply and divide recipes if you switch it over to metric. This is particularly useful if you don't have enough of one ingredient and need to reduce the others by that ratio.

Then there's the ability to measure the ingredient directly out of the container, using any scoop you can find, rather than needing multiple sets of measuring spoons.

I do find cooking easier in grams. Just put the bowl on the scale and add ingredients until it hits the number. No measuring cups to wash.

Uh, you know metric has volume measurements as well, and Imperial has weight measurements? Measuring cup vs scales is not really a difference in metric and imperial.
