About this worksheet

Fourth graders learn to change a measurement from a larger unit to a smaller one, such as feet to inches or hours to minutes. The key idea is that a smaller unit takes more pieces to make the same amount, so the number gets bigger. This fourth-grade worksheet has a conversion chart at the top and sixteen problems below it.

Part A gives ten conversions from a larger unit to a smaller unit, such as 7 feet = ___ inches or 4 kilograms = ___ grams. The problems mix customary units (feet, yards, inches, pounds, ounces, gallons, quarts, and pints), metric units (kilometers, meters, centimeters, millimeters, kilograms, grams, liters, and milliliters), and time. Part B gives six mixed measurements, such as 3 feet 4 inches, which students change into the smaller unit by multiplying and then adding the extra amount.

How to use it: read the conversion chart together first and point out the pattern: 1 foot is 12 inches, so 5 feet is 5 groups of 12. Students can make a two-column table, such as feet and inches, to see the pattern grow. For Part B, remind students to add the leftover inches or minutes after they multiply. The ten versions never repeat a problem.

The answer key lists every converted amount. This worksheet supports Common Core standard 4.MD.A.1 (know relative sizes of measurement units within one system of units and express measurements in a larger unit in terms of a smaller unit).
