Volume converters
Liters, US and UK gallons, cups, spoons, fluid ounces and cubic units. US and imperial measures are kept separate, because they differ.
Precision (significant figures)
Formula
gal = L × 0.264172
1 L = 0.264172 gal

Common situations
Why people usually need a volume conversion, and which tool answers it.
A US recipe asks for cups and tablespoons, and you have a metric jug.
US and metric cups are different sizes. The risk: dough that’s too wet or too dry.
What you need
The amount in mL, or in grams for dry ingredients.
Cups to MillilitersMilliliters to CupsCups to GramsTablespoons to Teaspoons
A tank or fuel price is given in gallons, and you think in liters.
A US gallon and a UK gallon differ by about 20%. The risk: using the wrong gallon and getting the cost or capacity wrong.
You’re ordering concrete, soil or mulch and the supplier sells by the cubic yard.
Your plans are in cubic feet or cubic meters. The risk: ordering too little and paying for a second delivery.
What you need
The order amount in the supplier’s unit.
