The estimate part of a millimeter when recording the block’s length can be expressed as ± 0.5 mm.
What are measurements?
Measurements are the processes by which the attributes and properties of a given object or substance is quantified.
There are two types of measurements that can be obtained from any given object and they are:
- quantitative measurements
- qualitative measurements
Quantitative measurements measures the properties of objects in terms of numbers. Some examples of quantitative measurements are length, temperature, time, mass, etc.
Qualitative measurements describe the non-numerical features of objects such as color, texture, etc.
Measurement of length of a block of wood is a quantitative measurement.
The uncertainty or estimate of the millimeter block = ¹/₂ * 1 mm = ±0.5 mm
