 To determine a measurement's absolute uncertainty, if:
 
  - the instrument states its uncertainty, use that.
- - an analog instrument is used, the uncertainty is half of the smallest scale. (eg if a ruler can measure to $0.1cm$, the uncertainty would $0.005 cm$)
+ - an analog instrument is used, the uncertainty is half of the smallest scale.
  - a digital instrument is used, the last reported digit is uncertain by 1 at its order of magnitude.
