1.6 kilometers per mile. Roughly one and a half times the distance in kilometers.

0.45 kilograms per pound. Roughly half the mass in kilograms.

I don't understand why we're NOT on the metric system. We're one of the only countries that doesn't widely accept the SI measurement. It's simple to use, and even simpler to scale to larger or smaller units. Ever try going from pounds to grams? What about quarts to ounces? Square feet to acres?

pounds to grams?

Were you thinking pounds to ounces? A pound is 16 ounces. There are 43 560 sq ft in an acre. There are 32 ounces in a quart.

An acre is 1 furlong long, and 4 rods wide.

660 x 66 feet = 43560 sq ft

Besides that, the Imperial system rules. An inch is the width of your thumb. You can take a foot, and divide by 2, 3, or 4, or 6 and get an even measurement. Try that with 304.8 millimeters. Unless you are lucky any division of a measurement by other that 2 will result in a fraction, and 1/2 of the divisions by 2 will result in fractions. Base 10 is horrible for units of measure. Now if they had used base 12 it would have been a different story.

metric is great for engineers. It SUCKS for people. How much is in a juice box? About 8 ounces, easy. In metric? 226 milliliters WTF? Which is easier? I can't imagine how tough it would be to try to cook with metric. I would go insane trying to get the right number of grams.

Heck, even Celsius sucks, the divisions are too big, end up going to fractions to get useful information.
