capacity refers to the lot that deserve to be hosted in a container. Capacity have the right to be measure up in metric units or in U.S. Customary units.

Metric devices

The typical metric unit of capacity is the liter.

indigenous the liter, we get the rest of the metric devices using the typical metric prefixes.

The eye dropper in the number has a 2 ml that liquid.

U.S. Customary systems

The system for measuring volume in the customary mechanism is based upon cup, liquid ounces, pint, quart and gallon.

In the figure shown, 2 cup of water is same to 1 pint.


The most frequently used customary systems of capacity space shown.

You are watching: What tool is used to measure capacity

1 liquid ounce (fl oz) 2 tablespoons that water
1 cup (c) = 8 liquid ounce (fl oz ) coffee cup
1 pint (pt) = 2 cups tiny ice cream container

1 quart (qt) = 2 pints

huge liquid measuring cup

1 gallon (gal) = 4 quarts

huge plastic jug of milk

To convert indigenous one unit come another, we deserve to use unit analysis . Because that Example, a glass the milk is higher than an eyedropper and also less than a tiny pitcher. Then calculation the capacity of glass the milk.


We understand that, 1 liter = 1,000 milliliters.

A small pitcher deserve to fill around 4 glasses.

One calculation for the volume of a glass the milk is around 1 , 000 ÷ 4 or 250 milliliters.


( a ) To convert from larger units to smaller sized units, main point by the appropriate unit ratio.

( b ) To transform from smaller units to bigger units, main point by the mutual that the appropriate unit ratio.
