Its quite simple , Miss Norway , and is as follows :-
An inch is the King's thumb from the middle joint to the end. ( = 25mm)
A foot was the King's foot . ( 300mm)
A yard was the King's stride = to 3 x King's feet.
There are 1760 yds in a mile , obviously.
There are 8 furlongs in a mile ( I think)
The money however is simple :-
2 Farthings = 1 halfpenny ( pronounced hay-penny)
2 Halfpennies = 1 Penny ( Hence 4 farthings = 1 penny)
6 Pennies = Sixpence or a Tanner ( So 2 x Tanners = a Bob)
12 Pennies = 1 Shilling (or Bob)
4 Threepenny bits = 1 shilling ( Pronounced Thre'pn'ey Bits (( also rhyming slang ))
2 Bob (Shillings) = 1 Florin ( or a 2 Bob piece) ( 10 Florins = 1 Pound )
30 pennies = a Half crown ( or Half a Dollar) (( expressed as 2/6d))
5 Bob = 1 Dollar ( expressed as 5/- )
2 Half crowns = 5 Bob.
10 Bob = 1/2 a Quid ( or a Ten Shilling note (( 10 Bob note))
20 shillings = 1 Pound ( Quid) ( 240 pennies = 1 pound) ( Obviously )
1 Guinea = 21 shillings ( 1 pound 1shilling) :C
