A bit of both. But I personally would like the world to go almost metric!
- Speed: I understand mph, km/h, Knots, m/s. Easy to convert.
- Length: I use Feet, Meters, NM. (mechanical i prefer mm prior to part of an inch, 3/8, 7/16 etc)
There use to be a EU Inch (Thumb of 2,96cm prior to the US/UK Inch of 2,54 cm)
I do not like mile: 5 280 feet, 1 760 yards, 1 609 Meters
There use to be 2 different miles (US and UK almost same except for 1/2")
- Temp: I prefer C. I understand 100F being body temp. BUT to have a feeling of 0F is more complicated. When a mixture of ice, water, and ammonium chloride freeze.
When water freeze and when boiling is understandable and rather useful.
- Volume: Liters.
I understand Gallon but do not like to use it. Can be US or Imperial Gallon (3,79L or 4,54L)
Isn't there liquid and weight lbs also?
BUT I really like the US style using (volume per distance) mpg. To know when to fuel up make sense. The EU style of using L/10Km is stupid. One have to recalculate. I would assume it originates from money perceived as more expensive then time.
As the the English man said: Inch by Inc we are getting closer to the metric system.
