Rock it like a Brit. Most things in metric except for your height (feet and inches) and your car speed (miles per hour) and when you measure your manhood (inches... Or fractions thereof).

Also, milk is pints.

Land is acres.

And the ponies run furlongs.

The UK continues to use miles when discussing speed and distance. The road signs use imperial units.

A few years ago I started using Celsius in my everyday life. It's been pretty easy, just remember that C scales twice as fast as F, and 32F=0C and you're set for conversations. It helps to be quick with math, but finding it difficult may make it easier to convince other people to use it instead of F near you. To acclimate yourself you'll want to change the settings on your phone to use C by default.

I haven't switched over to m in everyday use, because all the roadsigns are in Mph and doing that conversion while driving is bad juju.

I'm thinking of rewriting all my recepies in grams and liters. If I can figure out how to get our stupidly-over-designed-yet-entirely-jank oven to use C, that'd be good too. If we had one with a bimetalic strip and a knob I'd be able to just print one with the new temperature scale.

Technically the US is using the metric system. Per the Mendenhall Order of 1893, all customary length and mass units were redefined to be based on international metric standards. The Imperial system units commonly used in the US are just conversion factors of metric units.

Actually, we're on the metric system. The foot and inch are defined exactly by their metric conversion values, and so is the pound

We're actually just using conversion factors

Fine, fine, Ill use celsius.
