Units and Measurement

A self-checking practice quiz on units and measurement for an algebra-based physics course: SI units, derived units and metric prefixes, unit conversions, dimensional analysis, significant figures, scientific notation, uncertainty and error, orders of magnitude, and rearranging formulas. Every question is multiple choice and shown one at a time, and the set is drawn fresh each time you take it. At the end you receive a report showing how many you answered correctly.
