#a ramsden chain is 5 ropes = 20 steps = 40 paces = 200 shaftments

I've found my new favorite units chart (from wikimedia commons).

#units #graphs #I like that due to them only showing integer proportions you sometimes have to backtrack a lot to find common units to compare things #like Ramsden's chain vs Gunter's chain #a ramsden chain is 5 ropes = 20 steps = 40 paces = 200 shaftments #while a gunter chain is 4 rods = 44 cubits = 132 shaftments #so about two-thirds of a ramsden chain #(actually exactly .66 of a ramsden chain so a little under two-thirds) #also 'about half a foot' seems like a measurement that comes up a lot #so it's good to know that that's called a shaftment #definitely no off-color jokes to be made about that #also funny that they only show integer proportions *except* for the finger/inch ratio #which is 7/8 #I guess it just seemed to weird to have the finger floating off by itself
