I had an accident on my Harley

Gils, cubits...

I ran the low pressure lab at the national measurement laboratory for a while decades ago. You have all got it easy. Try doing high res calibrations of pressure instruments and converting on the fly between mmHg, inHg, MPa, KPa, psi, Bar, mmH2O, inH2O and about 20 others I can't even remember anymore....

I was young then and my brain still worked.

I hope this doesn't get this sent to the rubber room.

In another life I worked as a rear chainman on a survey crew. A chain by the way is 100 feet or 30.48 metres. Surveying in the US is based upon feet and 1/100 feet.

My survey party chief, or boss, once told me that feet and inches are only used by carpenters and whores. And that was one of the cleanest things that he ever said.

Nah, a chain is 100 links, or 66 feet. 100 links to the chain, 10 square chains to the acre, 80 chains to the mile....

Unless it isn't:

1 chain [Ramsden, engineer] to feet = 100 feet


1 chain [Gunter, survey] to feet = 66.00013 feet
