When taking measurements in a laboratory or clinical setting, it is vital that standard tools of measure are used so that measurements can be relatable and comparable.

However, if the same distance were said to be 0.457 km, since a standard metric unit is utilized, the measurement would be put in a quantifiable language that everyone can associate to a particular value. To start, let's first review how significant figures impact our measurements (accuracy and precision) as well as their impact on calculations
