What is a significant figure?There are 2 kinds of numbers:Exact: the amount of money in your account. Known with certainty.

What is a significant figure?
Approximate: weight, height—anything MEASURED. No measurement is perfect.

When to use Significant figures
When a measurement is recorded only those digits that are dependable are written down.

When to use Significant figures
If you measured the width of a paper with your ruler you might record 21.7cm.
To a mathematician 21.70, or 21.700 is the same.

But, to a scientist 21.7cm and 21.70cm is NOT the same
21.700cm to a scientist means the measurement is accurate to within one thousandth of a cm.

But, to a scientist 21.7cm and 21.70cm is NOT the same
If you used an ordinary ruler, the smallest marking is the mm, so your measurement has to be recorded as 21.7cm.
