I think in terms of ounces quarts and gallons. So, when you think in metric liquids, what's your reference?

Mine is a bottle of wine. 750ml. (.8 quarts) I can scale from that.

Length-
1" - 25.4 mm
1mm = .039 inches

Weight-
1 kg = 2.2 lbs (learned that one a long time ago)
1lb = .45 kg

What's your goto conversion references?

1. 28 grams to an ounce...

I don't really use it much, but I remember it...

3. I learned that one too, a long time ago.

2. 82 Fahrenheit is 28 Celsius

4. I go with a liter is just a little more than a quart. A meter is 3" more than a yard. 10k is 6.2 miles.

Your guides are good too. I'll add them to mine.

9. Your meter/yard is good.

100 miles/hr - 160 kilometers/hr. Easy to figure other ratios.

11. It's rough but my formula for km to miles is 5/3. It get's you in the ballpark.

5. Fuck up magas: Biden should declare US will move to complete metrication

Except for football yardage and ammo sizes.

It would drive magas mad and would draw the lines even clearer between the forward looking Democratic Party and the science-denying tRump Party, for all to see

Please, USA, go metric so we in Canada can get away from the awful hybrid hodge-podge forced on us by being caught between the world and the backward USA.

10. Lot of ammo is metric. 7.62mm (.3 in) is the small munition standard of the world.

6. Fifty Fahrenheit is 10 Celsius

-40 Fahrenheit is -40 Celsius.

[Bernardo de La Paz]

7. Tsp: 5ml, tbsp: 15 ml, quart about 1 litre, 10 cm snow 10 mm rain

Come to Canada. More metric than not.

8. Um...

A regular coffee mug and a soup spoon or the size of the puddle it makes in the bottom of the pan?

[OAITW r.2.0]

12. I am definitely not getting your post 2naSalit.

Maybe because I've already drunk 750 ml of a great Cabernet Sauvignon.

[2naSalit]

13. I usually use...

About a regular sized wine glass of that in most things I cook.

14. One hectare (ha) is approximately 2.5 acres (for quick calculation in head)

One hectare is more accurately 2.471054 acres.

15. I went to public school when education consisted almost entirely of conversions between systems of measurement

Even then, I wondered why so much time was devoted to conversions. Why not practice with the metric system without having to convert back to English measurements? The conversion really burned out many in my cohort. Getting into electronics in junior high, I had exposure to metric units all the time. College chemistry and physics used predominantly SI units. There was enough math already, and conversion would have pointless.

My favorite go-to conversion? 1 oz = 28 g

16. My husband and I were just commenting that we find it interesting...

...that English Premier League soccer talks about the "18 yard box" penalty area just like we do here in the US.

[LudwigPastorius]

17. 3.5 grams in an eight ball...

Oy! I'm glad those days are behind me.

18. For twenty years

I was an engraver and designer in the packaging industry. I don't know how many times I had to write or engrave
Net Wt. 50 Lbs. (22.68 kg) or 100 Lbs. (45.36 kg)
Usually rounded off to 22.7 or 45.4 kg
I'll always remember that.
A meter I figure is a yard plus about 3 1/2 inches. How that helps me I don't know.
Fahrenheit to Celsius - forget it. 32 will always be freezing and 72 room temperature to me.
