How does volume and capacity conversion work?
Volume measures the space occupied by an object or substance, while capacity describes how much a container can hold. ConvertAll uses the liter (L) as its reference unit. Each value is converted into liters and then into the selected destination unit using conversion factors. One liter equals exactly 1000 milliliters or one cubic decimeter. US gallons and imperial gallons have different capacities, so choosing the correct unit is important.
