• Change metric units of length, capacity, and mass. • • • Metric System: a decimal system of measures. Meter: the base unit of length (m). Liter: is the base unit of capacity (L). Gram: measures mass (g). Kilogram: The prefix for the base unit of mass (kg)

Convert Units in the Metric System Complete 7. 2 m = ? mm. To convert from meters to millimeters, use the relationship 1 m = 1, 000 mm 7. 2 × 1 m = 7. 2 × 1, 000 mm 7. 2 m = 7, 200 mm Answer: 7, 200 mm Write the relationship. Multiply each side by 7. 2. To multiply 7. 2 × 1000, move the decimal point 3 places to the right.

Complete 7. 5 m = ? cm. A. 0. 75 B. 75 C. 750 D. 7, 500 1. 2. 3. 4. A B C D

Convert Units in the Metric System Complete 40 cm = ? m. To convert from centimeters to meters, use the relationship 1 cm = 0. 01 m 40 × 1 cm = 40 × 0. 01 m 40 cm = 0. 40 m Answer: 0. 40 m Write the relationship. Multiply each side by 40. To multiply 40 × 0. 01, move the decimal point 2 places to the left.

Complete 3, 400 mm = ? m. A. 0. 034 B. 0. 34 C. 3. 4 D. 340 1. 2. 3. 4. A B C D

FARMS A bucket holds 12. 8 liters of water. Find the capacity of the bucket in milliliters. To convert from liters to milliliters, use the relationship 1 L = 1, 000 m. L 12. 8 × 1 L = 12. 8 × 1, 000 m. L 12. 8 L = 12, 800 m. L Answer: 12, 800 m. L Write the relationship. Multiply each side by 12. 8. To multiply 12. 8 × 1000, move the decimal point 3 places to the right.

BOOKS A box of textbooks has a mass of 32, 850 grams. What is the mass of the box in kilograms? A. 0. 3285 kg B. 3. 285 kg C. 32. 85 kg D. 328. 5 kg 1. 2. 3. 4. A B C D

Convert Between Measurement Systems Convert 7. 13 miles to kilometers. Round to the nearest hundredth if necessary. Use the relationship 1 mile 1. 61 kilometers. 1 mile 1. 61 km Write the relationship. 7. 13 × 1 mile 7. 13 × 1. 61 km Multiply each side by 7. 13 since you have 7. 13 miles 11. 4793 km Simplify. Answer: So, 7. 13 miles is approximately 11. 48 kilometers.

Convert 8. 15 gallons to liters. Round to the nearest hundredth if necessary. (1 gal 3. 79 L) A. 2. 15 L B. 30. 89 L C. 215 L D. 309. 1 L 1. 2. 3. 4. A B C D

Convert Between Measurement Systems Convert 925. 48 grams to pounds. Round to the nearest hundredth if necessary. Since 1 pound 453. 6 grams, multiply by . Multiply by Simplify. Answer: So, 925. 48 grams is approximately 2. 04 lb. .

Convert 5. 75 meters to yards. Round to the nearest hundredth if necessary. (1 yd = 0. 91 m) A. 6. 32 yd B. 5. 23 yd C. 0. 632 yd D. 0. 54 yd 1. 2. 3. 4. A B C D

FARMS Pike’s Peak near Colorado Springs, Colorado rises to a height that is 14, 110 feet above sea level. About how many meters high is Pike’s Peak? Since the height above sea level is 14, 110 feet, use the relationship 1 ft 0. 30 m. 1 ft 030 m Write the relationship. 14, 110 × 1 ft 14, 110 × 0. 30 m Multiply each side by 14, 110 since you have 14, 110 ft 4, 233 m Simplify. Answer: So, Pike’s Peak is about 4, 233 meters high.
