Litres, US units and cubic measures
The litre is the base unit, and a cubic metre is exactly 1,000 litres. The customary units here are US ones: a US gallon is 3.785 L, a US pint 473 mL and a US cup 236.6 mL.
UK imperial units aren't in the list. An imperial pint is 568 mL, about 20% bigger than a US pint, so a British recipe or beer measure won't match the US options. Divide by 0.568 if you need imperial pints.
The tool also can't turn volume into weight. A cup of flour weighs about 120–130 g while a cup of sugar is closer to 200 g, so for baking by weight you'll need the ingredient's density.

Good to know
US vs UK measurements
A US gallon is 3.785 liters. A UK (imperial) gallon is 4.546 liters, about 20% bigger. Same word, different amount. US cups and pints are also smaller than UK ones.
Worked examples
A 20 L water jar
That's 5.28 US gallons. The common office dispenser bottle in the US is 5 gallons, so the sizes are close but not the same.
Car boot space
15 cubic feet, a typical US figure for a mid-size sedan, is 424.8 L. European brochures quote litres, so this is how you compare.
Two cups of stock
2 US cups is 473 mL. A 500 mL carton covers it with a little left over.
Tanks and containers: litres to US gallons and cubic feet
Water tanks, aquariums, coolers and fuel cans are sold in litres in most of the world and in US gallons in America. Divide litres by 3.785 for US gallons and by 28.32 for cubic feet.

Dry pints, spoons and cubic yards
The pint, quart and cup in this tool are US liquid measures. The US also has a dry pint of about 550.6 mL, used for berries and other produce, so a "pint of blueberries" is a bit more than a pint of milk. Tablespoons, teaspoons and fluid ounces aren't in the unit list; the values in the quick reference above come from their definitions.
Concrete, mulch and soil are ordered by the cubic yard in the US, and one cubic yard is exactly 27 cubic feet. If you work out a patio in cubic feet, divide by 27 for the order quantity, then add a little extra for spillage and uneven ground.
