Paul,
Don't be silly. Use the metric system and you just measure it to the nearest ONE in sensible units. What is more simple than that for someone who needs to actually measure something in the field? And what is more, the rest of the world would know exactly what you are talking about.
Having used both systems, I can assure you the metric system is far better than the old Pound Shillings and Pence, Pounds and ounces, Rods, Perches and Yards, Feet and inches, Gallons quarts and pints, Ergs, British Thermal Units and many more. Don't tell me about quarters, thirds and sixths - the above all use a multitude of multiples and they were all thought up on a whim by people over a period of several centuries in the dark ages who were very good for their time, but unable to pull all the units together in one organised system.
The Americans were sharp enough to go for a decimal monetary system a long time ago, and I would think you don't even consider that this is so very much akin to the metric system!
The metric system is here and it works much better than the multitude of systems it made redundant - for both people in the field and behind desks.
As for further examples.
How did the Mars probe miss it's target - because someone got the wrong conversion factor? If only there was no need for a 'factor'.
Do you know why the Fahrenheit temperature scale has water freezing at 32 degrees? When it was invented the lowest attainable temperature in the laboratory was assigned as zero Fahrenheit!!!! Great idea at the time!!!!
Remember: 8 furlongs to the mile
10 chains to the furlong
22 yards to the chain
3 feet to the yard
12 inches to the foot
4 quarter inches to the inch
etc
So one mile seven furlongs three chains eighteen yards two feet seven and a quarter inches is how far? Who cares anyway? Just a stupid example of an unuseable system.
Metric system Standard unit is the metre
Smaller units have prefixes of deci, centi, milli, micro, pico, nano.
Larger units have prefixes of deca, centa, kilo.
Precision of measurement is easily understood by using scientific notation. Job done, easily, efficiently and the result can show the precision or accuracy perfectly clearly.
Same system basically applies for other quantities except time which has the second as the standard.
They are now all related as multiples of nuclear frequencies so as not to be mixed up anywhere in the known universe, but that is another can of worms!!
Regards and don't get too uptight about it, RAB

The Nuts and Bolts of Fasteners - Part 2 - by Curtis Von Fange. In our previous article we discussed capscrews, bolts, and nuts along with their relative hardness and thread sizes. In this segment we will finish up on our fasteners and then work with ways to keep them from loosening up in the field. Capscrews, bolts and nuts are not the only means of holding two parts together. When dealing with thinner metals like sheet tin, a long bolt and
