    May I present to you, how to measure like a Brit

    Flow chart showing the uses for metric and imperial in the UK

    It’s great fun especially when you’re trying to work out how fuel efficient your car has been when your tank and fuel pump is in litres and the fuel efficiency is in miles per gallon.

    Oh and you’ll have a jolly time following a recipe from more than 20 years ago trying to remember what the hell “Gas Mark 4” is in centigrade for fan or convection ovens.

    Oh and my personal favourite for the industry I’m in: when designing a PCB your component sizes will use imperial codes, your wire diameters will be in AWG, your track widths and PCB dimensions will be in millimetres, but your copper thicknesses will be in ounces despite the final weight for the assembly will be in grams.

      Bear in mind that the gallon we use is different from the US gallon, too:

      • a UK gallon is eight (imperial) pints of 20 fluid ounces, so 4.54 litres
      • a US gallon is 231 cubic inches, so 3.79 litres

      The reason that I thought American car fuel economy was so terrible as a child is partly because UK mpg is +20% on US mpg for the same car on the same fuel. But also, because American car fuel economy is so terrible.

      Canada has a similar chart, with some fun modifications. For example, distance could be feet/inches, millimeters/meters/kilometers, or minutes/hours, depending on what you are measuring.

        As an Indigenous Canadian … when someone asks me where something, someone, some town, some location, the sun or a celestial object is located … I turn my head and point with my lips.

        And my distance measurements are usually answered first by asking ‘why?’ … and if they give an acceptable response, I’ll tell them the distance is either … ‘not far’ … ‘far’ … or ‘very far’

      Thank you for posting this. So sick and tired of people saying that GB switched to Metric.

        This! That stupid map that just shows the US and Burma always annoys me. The US customary system includes Metric units. Canada and England still use Imperial/Customary. And “Metric” Is actually like 5 different systems with similar features like ANSI/ISO, KMS/CGS, and the three different pressure measurements.

        Natural units >>> Metric I want an alternative to Metric that uses base 12 units instead.

          Right?! I have been saying that for years! It really pisses me off that we evolved with 5 digits on each hand instead of 6. It’s clear evidence against the the idea of intelligent design.

            Cont on finger sections or knuckles, like some cultures do. Gives you 12 on one hand, using the thumb to count.

            Or 16 if you choose your reference points right.

              But we still have a number system where 10 is the sum of 5+5.

              I want a number system where 10 is the sum of 6+6, and 12 is the sum of 7+7. A number system with two more single-digit numbers: one representing the sum of 6 and 4 as a single digit; and another representing the sum of 6 and 5. A system where 10*10 is 100, and 100 is the product of 6 * 2 * 6 * 2. A number system where 10 is evenly divisible by 2, 3, 4, and 6.

              A metric system developed from that number system would be stunningly gorgeous.

      It’s because we’re stuck with a bunch of twats who can’t let go of the past. They’ll stick with Imperial measurements, mostly because the word looks like “Imperialist” and that’s the side they want to be on. Jacob Rees-Mogg is a wrought-iron dildo.

      Since volume is equivalent to metres cubed and distance is equivalent to metres (both multiplied by some conversion coefficient), I think fuel efficiency should be measured in metres squared, because why not.

      The only part I disagree with is stone/pounds for people’s weight. Although we use stone, I’ve never heard someone use pounds… Maybe if you’re in Weight Watchers or something, but otherwise it’d be rounded to the nearest half a stone (e.g. 9 and a half stone)

      A similar chart could be made for the US, proving that it does use metric: soda and wine bottles, medicine doses, eye-glasses measurements (in fact most medical things).

      I think that both systems are used in schools now.

      But then I see cooking instructions for a “cup of chicken strips” and a recipe having 1/4 cup of butter, and I wonder why anyone thought that volume was a good idea there.

          True, but that’s just replacing a cup with a length, and rules out using an existing tub.

          Why not use weight, which is easy to measure and tolerant of different forms/shapes?

            Butter in a tub usually isn’t pure butter as they add oil to it to make it spreadable when cold.

            Recipes that call for butter are normally designed for true/pure butter and may not cook or bake properly if spreadable stuff is used. (there is however Amish rolled butter that’s sold in big ‘loaves’ where measuring can be annoying)

            Weight requires a scale. I don’t know a single American who has a scale in their kitchen.

      your track widths and PCB dimensions will be in millimetres

      Not milli-inches? Is this a UK thing or have PCB design evolve since I last touched it?

      Anyway, milli-inches is one of the funniest unities I’ve used.

      Short distances should be meters, feet, inches, millimetres.

      None of that fractions of an inch bollocks.

      And milk is often actually in litres and half litres, we just assume it’s in pints. Clever little bit of shrinkflation.

        Short distances should be meters, feet, inches, millimetres.

        American machinists go a different way altogether: thousandths of an inch. So no binary fractions, but still imperial-ish. :/

        And milk is often actually in litres and half litres, we just assume it’s in pints.

        That one makes sense.

      Yes. Calculating how much a car journey is going to cost is such a chore. Trip in miles ÷ mpg × 4.5 × £/litre of fuel = cost.

        I just assume I’ll do 45.45 MPG, then I’m pleasantly surprised when the fuel bill is lower than expected.

      There’s also a difference between imperial miles and nautical miles, though I’m not sure if British long distance ships use nautical miles or not.

      You forgot that inside temperature is in Fahrenheit, outside is in Celcius.
