None, really, because a gallon is not a metric unit. A litre is the appropriate unit to use for measuring volumes.
A pipe has the shape of a cylinder; just use the formula for the volume of a cylinder. In metric units, you have the advantage that the units are consistent. For example, if the radius and height of the cylinder are measured in decimeters, the volume will be in cubic decimeters (= liters).
That one!
Metric ruler
liter
The gram.
To find the area of a book cover in metric units, the most appropriate unit to use would be centimeters. The formula for finding the area of a book cover would be: length x width.
If it's a standard book, the standard units would probably be cm2.
The volume is measured in litres. 1 cubic decimetre (dm³) is 1 litre.
A metric ruler measures in inches and centimeters.

1 US gallon = 16 US Cups (exact) = 15.14 Metric cups 1 Imperial Gallon = 19.215 US cups = 18.18 Metric cups Ans 2 I would agree totally on your US measurement, but in the rest of the world, a 'cup' is a nebulous amount and I think depends on which country you are in. In UK, a cup is half of an Imperial pint. I cannot find a 'metric cup' defined anywhere with authority, and your amounts specified above make it exactly half a litre - (that's a very large cup). This entire issue is further complicated by the usage of 'liquid'cups and 'dry volume' cups, and the use of ISU or SI (International System of Units) in some countries instead of 'original'Metric. A very confusing issue indeed! 1 gal = 16 cups 1 cup = 0.06 gal 1 gallon = 16 cups 1 cup =0.23 gallon User Avatar
You would use meters.
Grams.
Millimeter
The kilogram.
