Ever wonder who decided what 'standard units' of measurements should be? A "foot" got its name from the length of King Charlemagne's tootsie. An inch was the distance between knuckles on King Edgar's index finger. A yard was the distance between King Henry I's nose and thumb. The distance of a mile was determined by counting 1,000 steps of a Roman Legion. Standard units of measure make it easy to communicate size and shapes. If you are out shopping and don't have a ruler handy, just take out a quarter. It's exactly 1 inch across or a dollar bill, which measures 6 inches across. And that's the On The House tip for today.
