Only 40 rods!! That's very wasteful I blame the cheap fuel policy in the U.S. Actually chains, rods, poles( they are interchangeable)and then furlongs and acres all have a logical interconnected basis going back to the Middle Ages. Trouble is we no longer need to rely on medieval measurements which belong to times when precision and easy division wasn't required. Most couldn't read or write never mind do any math,. Add the "s" if you are in the U.K.

You wouldn't guess temps so why guess weights as little as a tenth of a gramme which in some cases are more critical
