For all of those people who think the metric system is too hard, I have a question.
Without a calculator, how many inches in a mile?
Got the answer? It’s 5280 feet x 12 inches per foot.
Do it in your head
It’s 63,360 inches
How about a nautical mile?
6076 feet x 12 inches per foot totals 72,912 inches
Now, how many millimeters in a kilometer?
1000 millimeters per meter x 1000 meters per kilometer equals 1,000,000 millimeters.
Still think metric is hard?
