Teaching Significant Figures Using Age Conversions

Abstract
In this classroom activity the instructor provides increasingly precise values of the age in years of a famous person to have students calculate the age in days. An accurate age is readily determined using Julian dates. The activity provides a student-friendly, equipment-free entry to a discussion of estimated measurements, significant figures, exact numbers, rounding, and conversion factors.
