Metric Units: Length, Capacity, & Mass

By Michelle Taylor

I can describe the relationship between metric units of measurement.

​

MGSE4.MD.1 Know relative sizes of measurement units within one system of units including km, m, cm; kg, g; lb, oz.; l, ml; hr, min, sec. a. Understand the relationship between gallons, cups, quarts, and pints. b. Express larger units in terms of smaller units within the same measurement system. c. Record measurement equivalents in a two column table.

Metric Units of Measurement

Length

1 millimeter (mm)

It is very small.

1 centimeter (cm)

1 cm = 10 mm

1 meter (m)

1 m = 100 cm

1 m = 1000 mm

1 kilometer (km)

1 km = 1000 m

​250 mm = __ cm

​

​

3,000 km = __ m​

​

​

500 cm = __ mm​

​

Metric Units of Measurement

Capacity (Volume)

Capacity or Volume

This is a measurement for the amount of space to fill something. It is commonly used for liquids.

Milliliter (ml)

A very small amount, a drop.

Liter (l)

1 l = 1,000 ml

​1,000 ml = __ l

​

​

​50 l = __ ml

​

​

100 l = __ ml​

​

​

Metric Units of Mass​

Gram (g)​

​Light. The weight of a pen or a grape.

Kilogram​ (kg)

​Heavier. The weight of a water bottle or a pineapple.

John has 50 water balloons that will hold 300 ml of water each. How many liters of water will he need to fill all the balloons?

​10 kg = __ g

​

​

10,000 g = __ kg

​

​

2 kg = __ g​
