My sister was teaching third grade math at the time. She said that her students found the metric system (SI) much easier to understand than the U S Customary “system”. U S Customary is such a mess that I cannot logically call it a system. It’s time for U S Customary measurement to join Roman numerals in the relic box of history.
Back in the 70s it was thought that we would be fully converted to the metric system within 10 years. It seems ridiculous to keep the antiquated British system, which not even the British use anymore.
I really hope that it is not influenced much by people hoping to keep records in sports like football intact.
