The short story:
- I’m on holiday.
- Maps are cool.
- For more, read my first post of 2015: 2015, and Mapping The Way Forward.
Countries that make it complicated:
Which is a bit of a mystery, not so?
Some comparisons from www.metric.org.uk:
Comparing metric with imperial
|It is consistently based on decimal numbers||It uses different number systems (base 3, 8, 12, 14, 16, etc)|
|Works well with percentages||Percentages are difficult to work out (Try deducting 10% from your body weight in stones and pounds!)|
|Able to deal with very large and very small quantities (using prefixes based on powers of ten)||Large units limited in size and have an awkward relationship to smaller units. Small quantities handled with awkward fractions|
|One sort of unit for weight:
||Two systems of weight:
|One system of volume:
1000 millilitres = 1 litre,
|Two systems of volume:
(How many pints in a cubic foot?)
|Handles mechanical and electrical quantities||No electrical units. Mixing imperial mechanical units and metric electrical ones is messy|
|Units are the same internationally||Some units differ between UK and US
|Simple calculations such as floor area, energy consumption and volumes are easy||Simple calculations such as floor area, energy consumption and volumes are needlessly complicated|
