I'm sitting in Australia with my son, having fun, doing the "Units" section and we get this question:

"An alien rocketship is traveling at a speed of 0.028 miles per second. At this speed, how many feet will it travel in 1 minute? Round to the nearest thousandth."

Having grown up in Australia (and I'm 43 years old), I have no idea how to translate feet into miles.

Could I suggest having a "metric" option so that we don't get asked such questions? (Same goes for quarts and gallons!)

Thanks!
