Conversion Definitions
Litres: A litre is a metric unit of volume equal to one cubic decimeter (dm³), which is the space occupied by a cube measuring 10 centimeters on each side. Litres are used globally to measure liquids and sometimes solids, especially in scientific, culinary, and commercial fields. It’s a standard unit in most countries except the US.
Gallons: A gallon is a unit of volume used in the US and some other countries. There are different types, but the US liquid gallon equals about 3.785 liters. It’s commonly used for measuring larger quantities of liquid such as gasoline, milk, or water. The gallon measures volume but varies by region.
Conversion FAQs

Is it accurate to round gallons to four decimal places?
Rounding to four decimal places provides a practical balance between precision and usability for most applications. For high precision needs, more decimal places might be required, but for everyday use, four decimals are sufficient.
How do temperature changes affect litre to gallon conversion?
Volume can change slightly with temperature due to expansion or contraction, but the conversion factor itself remains constant. For extremely precise measurements, temperature effects on volume should be considered, but this is rare in casual conversions.
