Measurement and Precision

The Role of Numbers in Measurement

Measurements use real numbers, and understanding precision is key in science and engineering.

Why Precision Matters

  • Ensures accuracy in experiments
  • Affects the outcome of engineering projects
  • Important for health and safety (medicine, construction)

Handling Units and Decimals

Always pay attention to units (meters, grams, liters) and use decimals for greater precision.

Real-World Example

Precision can be the difference between a bridge standing or falling, or a medicine dose being safe or dangerous!

Examples

  • Measuring the length of a table to the nearest millimeter.

  • Recording precise temperatures in a science experiment.
