Metric Units of Length 1 mm = 0.1 cm 1 cm = 10 mm 1 m = 1000 mm 1 mm = 0.001 m 1 cm = 0.01 m 1 m = 100 cm millimeter centimeter

Steps for Measuring Length Always start by lining up the object you’re measuring with zero on the ruler. Hold the ruler with your left hand. Read the last number on your ruler that is below the object.

Let’s Practice! 7 centimeters

Steps for Measuring Length If the object’s length doesn’t land exactly on a number, read the closest centimeter to the left. Next, count the number of millimeter marks. Remember that a millimeter is 1/10 of a centimeter. 2 centimeters (2 cm) + 8 millimeters (0.8 cm) = 2.8 cm

Let’s Practice! 4 centimeters (4 cm) + 6 millimeters (0.6 cm) = 4.6 cm

Measure to the nearest millimeter 4 centimeters (4 cm) + 6 millimeters (0.6 cm) = 4.6 cm 4.6 cm X 10 = 46 mm

Measure to the nearest meter 5 centimeters (5 cm) + 1 millimeters (0.1 cm) = 5.1 cm 0.51 m

Let’s Practice! 5 centimeters (5 cm) + 7 millimeters (0.7 cm) = 5.7 cm

Measure to the nearest meter! 5 centimeters (5 cm) + 7 millimeters (0.7 cm) = 5.7 cm 0.57 m

Measure to the nearest millimeter! 5 centimeters (5 cm) + 7 millimeters (0.7 cm) = 5.7 cm 57 mm

in your math notebook Daily Check 3.2 Measure the length on the title “Mixed Review” on page 129 to the nearest tenth of a centimeter. The seat of a chair is exactly 43 centimeters from the floor. Write that distance in millimeters.
