What is Calibration?

Calibration of measuring device is distance between two closest two closest lineslines

(NNotot distance between two closest #!)

Not all graduated cylinders are calibrated the same way

Calibration = ?Calibration = ? 1 ml1 ml

Calibration = ?Calibration = ?1 ml1 ml

Calibration = ?Calibration = ?0.2 ml

Here are some other pieces of lab equipment.

Can you figure out the calibration of each?

meter stick: two closest lines are 1 millimeter apart

Calibration = ?Calibration = ? 50 ml50 ml

Calibration = ?Calibration = ?25 ml25 ml

This is a quadruple beam balance

What’s the calibration? 0.01 gram

This is a buret [unlike graduated cylinder, numbers go down, so you read downwards]

The calibration is:

0.1 ml0.1 ml

So why is knowing calibration important?

When you measure you measure to one place past the calibration.

You told me the calibration was 1 ml, so the answer has to go to 1.0, 1.1, 1.2, 1.3, etc
