As a kid, I read quite a few books that had British authors. Most of the time, I understood what they had written. Fortnights gave me a bit of a problem – but I figured out that meant two weeks. Furlongs weren’t much of a problem – an eighth of a mile is 220 yards on either side of the Atlantic – but their currency was downright confusing. About 50 years back, they went over to 100 pence equaling a pound – but the old books still contain the confusing old system. I picked up this explanation from Glen Filthy – an Alberta blogger – http://filthiestbox.blogspot.com/
