My friend Ken says - You forgot lots of others - including (but not limited to): Furlong (still in everyday use in the racing industry) Ell (one and a quarter yards) Dram (or Drachm if you prefer) Stone Sack Scruple Carat (stil in everyday use) Knot (still in everyday use in marine and aviation) Fathom (still in everyday use) Pint Gallons (of course) Bags and Buckets (24 and 4 gallons respectively) Barrel (42 US Gallons - still in everyday use in the oil and petrochemical industries). Firkin (9 Fallons - still in use in the brewing industry) Minim (1/60th of a fluid ounce) League Link Cable Rod (length - not to be confused with Rood which is area) Rope (20 ft - still in use in marine and lifting/rigging) Span (9 inches - still used by brickies) BTU Puoundal Horsepower PSI I guess my point is that in in those "superior" countries where metrication= is regarded as being pretty much complete, many (but not all) of the old units= are still in everyday use in one industry or another. Farthingdale is a good one and actually has two different measures. The mo= st common is 1/4 acre which is the same as a rood which is 40 perches - and w= hich is within 0.1% of 0.1 hectare (hence 5 acres is very close to 2 hectares). Compound units can be fun too: Litres per hundred km is dimensionally equivalent to an area for instance = - my car does xxx acres (substitute favourite unit of area). Try to think hard = about what that means. Then we have the various abominations like metric inches (25.0mm) - loved = in plumbing. Measurements of angles and time have never been metricated to any significa= nt extent (though some have tried).
