Sig Figs Significant Figures – the reliable digits in
a measurement based on the precision of the device
In other words, the MORE sig figs it has the more PRECISE the number is

Why are Sig Figs important?
Let’s say I measured the area of the basketball court.Trial 1: Estimate by walking: About
15m wide by 26m long
- Area is about 390m2
Trial 2: Actually measure: 15.24m wide by 25.60m long
- Area is 390.1 m2
