Conversion between Imperial and Metric values

Description

Routines to convert between imperial and metric values.

Note:
When converting from cm to feet and inches, the inches are the first 2 (!) digits after the decimal point. When converting feet and inches to cm, the input must be in the form f.iijj, i.e. ii inches, jj fractions of an inch.

Examples:

A VW "Käfer" ("Beetle") 1303 from the early 70s had a fuel consumption of 10 l/100km: 10 GSB . 2 = 23.5 mpg as a US "Beetle" or 28.2 mpg in the UK.
A Chevrolet Corvette ZR1 (2020) has an est. Highway fuel economy of 19.0 mpg (22.8 mpg in the UK): 19 GSB 2 = 12.4 l/100km.
Dirk Nowitzki is 213 cm or 6 ft 11.86 in tall: 213 GSB . 3 = 6.1186
The Clock Tower of the Palace of Westminster ("Big Ben") is 315 ft or 96 m tall: 315 GSB 3 = 9,601.2000 (≈96 m)
