The foot is a unit of measure with the base unit being 1. Therefore a kilofoot (Kft) is 1000 feet. 12000 is a kilofoot expressed in inches. Inches were further divided by 10, 100 and 1000, or, 2, 4, 8, 16, 32 and 64. Twist drills were the latter whilst engineers used a micrometer calibrated in thousandths of an inch. You figure it out! Metric units may not be for everyone but we did one really useful thing when we decimalised our currency, which used to be pounds, shillings and pence. 12 pennies to a shilling and 20 shillings to a pound. Of course, if you're old enough we had half-pennies and even earlier, farthings which were a quarter of a penny. Now we don't even have 1 and 2 cent coins, although those still lingering about are still legal tender. Our smallest coin is now the 5 cent piece. We managed to make a lot of wealthy people millionaires overnight on the 14th February 1966, when decimal currency was introduced, because the pound became 2 dollars. Ray vk2tv
