Key Stage 4

Meaning

Resolution is the smallest change a measuring instrument can detect.

About Resolution

The resolution of a measuring instrument is given by:

The markings on an analogue instrument (such as a ruler or thermometer).
The number of significant figures on a digital instrument (such as a digital ammeter or data logger).

If the markings on an analogue measuring instrument are far enough apart it may be possible to tell to the nearest 'half' of a division.

Examples


This ruler has a resolution of 1mm. The position of each end of the object can be read from the ruler as close to 6.4mm at one end and close to 8.8mm on the other. It is not possible to tell its length more precisely than to the nearest millimetre.

	This thermometer has a resolution of 1°C. It is not possible to tell the temperature more precisely than to the nearest degree. However, many thermometers have a large gap between the markings and it is possible to tell when the line is half way between them. This gives many thermometers resolution of 0.5 degrees.
