1 Metrics Review Name: Period: You will need a metric ruler and ten pennies for this activity. LENGTH 1. What does each unit represent? (a) mm = (b) m = (c) cm = (d) km = 2. How much does each one equal? (a) 1 m = cm (b) 1 cm = mm (c) 1 km = m 3. Which measurement is the largest? Circle your answer for each pair. (a) 14 mm or 1 cm (d) 145 m or 145 km (b) 334 m or 1 km (e) 3.4 cm or 30 mm (c) 1 m or 990 cm (f) 10 km or 1000 cm 4. Use a metric ruler or meter stick to find each measurement. (a) Length of the line in centimeters (b) Length of the line to the nearest centimeter (c) Height of the rectangle to the nearest millimeter (d) Width of the rectangle to the nearest millimeter (e) Radius of the circle to the nearest millimeter (f) Diameter of the circle in centimeters (g) Diameter of the circle to the nearest centimeter HINT: If it says nearest, you need to round your answer so you don t have a decimal point. If not, you should have one decimal point in your answer.

2 (h) Volume of the box in cubic centimeters x x = (Measure to the nearest centimeter before multiplying.) 5. Find the length of an unsharpened pencil (including eraser) in millimeters. 6. What is your height in centimeters? What is your height in meters? 7. Use ten pennies and a metric ruler to complete this section. (a) How tall is a stack of ten pennies in centimeters? (b) How tall would a stack of 1000 pennies be in centimeters? 8. Circle the BEST metric unit for each. (a) The length of an eyelash mm cm m km (b) The height of a flagpole mm cm m km (c) The length of a strand of spaghetti mm cm m km (d) The distance from Laguna Hills, CA to Phoenix, AZ. mm cm m km 9. Make the following metric conversions (show your work using the moving the decimal method ): a) 25 mm = cm b) 4.56 cm = mm c) 2.5 mm = m d) 75.2 cm = m e) 350 cm = mm f) 0.45 m = cm

3 MASS 10. The base unit of mass in the metric system is the and is represented by. 11. refers to the amount of matter in an object. 12. Complete each statement. (a) 1 kg = g (b) 1 g = mg 13. Which is larger? Circle your choice for each one. (a) 1 kilogram or 1500 grams (b) 1200 milligrams or 1 gram (c) 12 milligrams or 12 kilograms (d) 4 kilograms or 4500 grams 14. What instrument will we use to find the mass of objects? 15. Make the following metric conversions (show your work using the moving the decimal method ): a) 1,500 g = kg b) 0.08 kg = g c) 0.05 kg = mg VOLUME 16. is the amount of space an object takes up. 17. The base unit of volume in the metric system is the and is represented by. 18. Which is greater in volume? Circle your choice for each one. (a) 1 liter or 1 gallon (b) 1 liter or 1 quart (c) 1 milliliter or 1 fluid ounce 19. Which is larger? Circle your choice for each one. (a) 1 liter or 1500 milliliters (b) 200 milliliters or 1.2 liters (c) 12 cm 3 or 1.2 milliliters* 20. What instrument will we use to find liquid volume? 21. What formula do we use to find the volume of regular objects? Volume = X X

4 22. Make the following metric conversions (show your work moving the decimal ): a) 10 L = ml b) 750 ml = l c) 0.5 kl = ml USING a GRADUATED CYLINDER to measure volume. When a liquid is placed into a glass container it forms a meniscus, a curved surface that is lower in the middle than at the edges. To determine the volume of liquid, use the number that is directly at or below the bottom of the meniscus. Read to the unit the graduated cylinder is marked off in (your certain digits) THEN ESTIMATE ONE MORE PLACE (your doubtful digit). If the graduated cylinder is marked off in units of one, your volume reading must go to the tenths place in order to have your doubtful digit. Example: Using a 100 ml graduated cylinder (marked off in units of ones, the bottom of the meniscus is between 52 and 53, but closer to 52 than 53. You read it as 52.4 ml, with the 4 being your best estimation of where the bottom of the meniscus is. You are certain of the 52, the 4 is your doubtful digit. 23. Read and record the volume of liquid in the graduated cylinders below. a) b) c) d)

5 24. How could you find the volume of an irregular object (like a small rock) using a graduated cylinder? TEMPERATURE 25. What is the basic unit for temperature in the metric system? 26. What are the freezing and boiling points of water on this scale? 27. Circle the best choice: a) Temperature on a hot summer s day: 0 o 35 o 90 o b) Room temperature: -20 o 0 o 20 o 28. Convert the following temperatures. Show your work! C = (F-32) x 5/9 F = (C x 9/5) + 32 a) 65 C = F b) 15 C = F c) 105 C = F d) 72 F = C e) 117 F = C f) 56 F = C
