Rule of Measurement

Metric is better by 1000.

One kilo-better
Found the vegan!
- I also use metric. I eat whale. Last time I checked, a 300g whale burger isn't vegan, gun monkey!

Here’s a handy guide to SE:

1 liter = 10 deciliter

1 deciliter = 10 centiliter

1 centiliter = 10 milliliter

Base 10 vs base 2

Unless it’s butane. Butane is lighter fluid.

Butane's a bastard gas
- I'll tell you what.
What would that be measured by?
- It's lighter so you can't measure it
- volume? at least here thats how its measured when you get that mixed 60/40% with propane (i think) for your car as LPG. but then its under pressure and due to that a liquid

I live in a country where these measurements aren't used, so without any background knowledge I interpreted the comma as "and" at first. Looking at the picture, I'm pretty sure it's meant to be "or" instead, in which case they should have used a slash instead of a comma imo.

But most actual cups are 200ml, whereas a pint is 470ml. So if you use a real cup as a measuring tool you are short on the pint.

A cup is 236 ml. I was always taught 240 ml but google converts to 236.
- Thanks for proving how stupid of a measurement a "cup" is
- Currently used definitions of the cup:
  
  The US customary cup (236.6 mL) is 8 US customary fluid ounces. The US customary fluid ounce (29.6 mL) is 1/16 of a US fluid pint.
  
  The US legal cup (240 mL) is 8 US nutritional fluid ounces. The US nutritional fluid ounce is 30 mL.
  
  The metric cup is 250 mL
  
  Historically used definitions of the cup:
  
  Ths British cup (284.1 mL) is 10 imperial fluid ounces. The imperial fluid ounce (28.4 mL) is 1/20 of an imperial fluid pint
  
  The Canadian cup (227.3 mL) is 8 imperial fluid ounces
An American pint is 470 ml a British pint is 568 ml, and a french Canadian pint is 1136 ml.
- Hell yeah Canada!! une pinte de bière s'il vous plaît !

Murica moment

There are 20 fl oz. to a pint

Instead of cups you should use half pints.

There are 8 pints to the gallon.

Unless you specify which pint, gallon then you're probably wrong anywhere outside the US. Even then you could have to deal with vintage Canadian equipment with imperial labeling.

US Cups are random in measurement and only sometimes half a pint.

The imperial fluid oz. has one value 28.413 ml

The US fl. oz used to be 29.573 ml. But now can officially be 30 ml in some settings.

Metric is the best system, followed by imperial which at least is still a consistent standard.

Then US customary measures where the written value may or may not have to meet a standard these days.

The US has been using metric for everything important for a long time now like the rest of the world. Except the Mars probe NASA crashed.

Correction, NASA only uses metric. Lockheed Martin was contracted for some systems and that's where the unit conversion problems came from.

Still partially NASA's fault for not checking / enforcing units.
- Thanks.
  
  Important to put the blame where it actually lies.

I can actually feel my brain cells dying

This is very confusing. I assumed at first that a gallon was 4 quarts + 8 pints + 16 cups, a weird way to write 8 quarts.... Because a quart in my interpretation is 2 pints + 4 cups = 8 cups. I mean the diagram does show the gallon containing all of them.

quarter-gill nipperkin and a round bowl!
