Chapter: Geometry And Measurement
Measurement systems provide standardized ways to describe and compare physical quantities. The two major systems are the metric system, widely used worldwide and in science, and the United States customary system (USCS), mainly used in the U.S. A third related system, the International System of Units (SI), is the modern global standard. Understanding conversions, unit selection, and estimation ensures accurate problem solving in both academic and real-life contexts.

Time
- Units: second (s), minute (min), hour (h), day, week, month, year
- Conversions: 60 s = 1 min, 60 min = 1 h, 24 h = 1 day, 365 days ≈ 1 year
