The other day you worked with converting meters, centimeters, and millimeters. Here are some more unit conversions.
1. Use the equation below, where F represents degrees Fahrenheit and C represents degrees Celsius, to complete the table.
2. Use the equation c = 2.54n, where c represents the length in centimeters and n represents the length in inches, to complete the table.
3. Are these proportional relationships? Explain why or why not.
