Volume converter moves a value between l, ml and m3 and the US gal, qt, pt and floz. Litres are the base, and the four non-metric units are US liquid: a gallon is 3.785411784 l. The imperial gallon of 4.54609 l is absent, and it runs about a fifth larger.
Questions
Which volume units are supported?
Seven: l, ml, m3, gal, qt, pt and floz. Liters are the base, so a milliliter is 0.001 l and a cubic meter is 1000 l. The four non-metric units are the US liquid ones: a gallon is 3.785411784 l, a quart 0.946352946 l, a pint 0.473176473 l and a fluid ounce 0.0295735295625 l.
Are these US or imperial gallons?
US liquid. gal is 3.785411784 liters, the US gallon. The imperial gallon of 4.54609 liters is not in the table and is about 20 percent larger, so a fuel or recipe figure from the UK will convert wrongly if you assume otherwise. The same goes for pt and floz, which are US sizes here.
Is floz a weight?
No, it is a volume: the US fluid ounce of 0.0295735295625 liters. The ounce that weighs something is oz in the mass converter, and the two are not interchangeable. A fluid ounce of oil and a fluid ounce of honey have different masses, so a recipe given in grams needs the mass tool.
Can I convert liters into kilograms?
Not here. That needs the density of the substance, which this tool neither knows nor asks for. Water is the case people remember, where a liter is roughly a kilogram, but that is a property of water rather than a unit relationship. Volume units stay in the volume converter.
How do I enter the value?
As a bare number in the value field, with the unit chosen in the from dropdown. Anything that does not parse gives "value must be a number", which usually means a unit was left in the box or a comma was used as the decimal point. The result prints as one line, such as 1 gal = 3.785411784 l.
