Convert units with conversion factors so units cancel: hours to seconds, feet to centimeters, gallons to cups. There are 2 sheets here: unit conversions and metric conversions. Pick one from the tray, print it, and add its answer key as a second page if you want one.
Write each conversion factor as a fraction so the units cancel. Exact factors: 1 in = 2.54 cm; 1 qt = 4 c.
They suit grades 8 to 12. Each sheet in the tray practices it a different way, so you can pick the one that fits.
