This interactive tutorial provides practice in using dimensional analysis to do metric conversions and validate the conversion factors in equations. Students are first guided through two example problems, then progress to exercises requiring self-solving. Users may click to add conversion factors or select units from a drop-down menu. Helpful tools include a "Pencil and Eraser" that allows students to draw lines for cancellation of units, and a "Balance" tool that tells them whether their conversion factors are valid.
This resource is appropriate for students of high school physics.

Topic: Measurement and the Language of Physics Unit Title: Dimensional Analysis
Dimensional analysis (DA) is a technique that is used to change any unit from one to another and to validate equations. Students who understand DA have a definite advantage in solving problems. This terrific interactive tutorial starts with slowly-paced guidance, then progresses with conversion problems. Cool tools include a "Pencil & Eraser" allowing students to draw lines to cancel units, and a "Balance" tool to tell them whether their conversion factors are valid. Requires Shockwave plug-in.
