The benefits of using mercury:
How to increase the sensitivity of a mercury thermometer
Thermometer calibration
To do this, two extreme points are chosen to mark its scale and these points must be able to be reproduced accurately.
where \(\theta\) = temperature, \(l_0\) = length when temperature is \(0\;^0\text{C}\), \(l_{100}\) = length when temperature \(100\;^0\text{C}\)
