Conversion Graphs C) This graph shows the conversion rate from degrees Fahrenheit to degrees Celsius. 40 25 Use the graph to complete this table. 20 Remember, we estimate when reading from a graph. 15 10 5 0 0 2 4 6 Inches 8 10 Inches Centimetres 6 15 4 10 9 23 2 5 5 13 7. 5 19 Describe how we can use the graph to convert 80 inches to centimetres. Kilometres °C 20 10 0 30 40 50 60 °F 70 90 80 What is different about this conversion graph? 1) 70°F ≈ 21°C 2) 47°F ≈ 8°C Does not cross (0, 0) 3) 24°C ≈ 74°F 4) When water is frozen, what is approximate temperature in °F? Find 8 inches, multiply by 10. B) 30 32°F (85 − 32) = 53 85 + 53 = 137°F 5) Use this fact to convert 60°C to °F. 10 5 miles ≈ 8 kilometres 0 miles = ? kilometres 8 Use these data points to plot a conversion graph. 10 6 Use this line to complete the table. 8 A different car costs £ 5 to go 13 miles. Draw the conversion line for this car. 6 Approximately how much does it cost each car to travel 40 miles? 0 4 2 0 0 2 4 6 Miles 8 10 Miles Kilometres 2 3 3 5 12 18 -20 6 10 4. 1 -4. 4 7 41 -44 70 30°C = 85°F D) Cost £ Centimetres A) This graph shows the conversion rate from inches to centimetres.
