There are at least a couple of ways. Each may not be appropriate in all circumstances.
- Read the measurement from markings between those that are numbered. For example, most rulers have numbered centimetres but the markings are at millimetres.
- If there are a number of identical items, then measure then together and take their average. For example, if you have ten identical coins, then the measure their combined mass and divide the answer by 10. That average will have one more sig fig. But the items MUST be identical.
