I just saw a news article about water conservation that gave a measurement in acre-feet. We’ll do anything to avoid the metric system 😂

(One acre-foot is on the order of 103 cubic meters, or 10−6 cubic kilometers. So neither of those is a great alternative if you’re starting with a “human-sized” number of acre-feet.

But! An acre-foot is ~0.1 hectare-meters. If you have a number that is convenient to work with in acre-feet, it would probably be convenient to work with in hectare-meters too.)
