Featured Measurement Practice
Metric Measurement Conversions Practice
Practice converting between metric units: meters/centimeters/kilometers, grams/kilograms/milligrams, and liters/milliliters.
Customary Measurement Conversions Practice
Practice converting between customary units: inches/feet/yards/miles, ounces/pounds/tons, and cups/pints/quarts/gallons.
Metric Length Conversions Practice
Convert between metric length units: kilometers, meters, centimeters, and millimeters. Metric conversions use powers of 10.
Metric Mass Conversions Practice
Convert between metric mass units: kilograms, grams, and milligrams. Mass conversions are essential for cooking and science.
Metric Capacity Conversions Practice
Convert between liters and milliliters. Liquid measurement conversions are used daily in cooking and science.
Customary Length Conversions Practice
Convert between customary length units: inches, feet, yards, and miles. These conversions are essential for everyday US measurements.
Customary Weight Conversions Practice
Convert between customary weight units: ounces, pounds, and tons. Weight conversions are used in cooking, shopping, and science.
Customary Capacity Conversions Practice
Convert between customary capacity units: cups, pints, quarts, and gallons. Capacity conversions are essential for cooking and recipes.
Temperature Reading Practice

Free Measurement Conversion Quiz
Measurement conversion is one of those topics that rewards memorization of a few key relationships — 12 inches in a foot, 16 ounces in a pound, 1000 grams in a kilogram — and then the rest is multiplication. This quiz mixes customary (US) and metric units so students don't develop blind spots in either system. The metric conversions are arithmetically easier (everything's a power of 10), but the customary ones come up more in everyday US life. Either way, regular practice beats cramming for the test.
