Standards are the fundamental reference for a system of weights and measures, against which all other measuring devices are compared.

Measurements continue to play an important role throughout everybody’s life, for example, during a medical check-up, a sports competition, when building a house, when controlling temperature in appliances, or while cooking.
What are the applications of measurement?
Application of Measurement Systems
- Monitoring of process and operation- simply indicating the value or condition of the parameter under study.
- Control of process and operations- automatic control system a very strong association between measurement and control for example -refrigeration with thermostatic control.
Why do we need to learn the two system of measurement?
To avoid confusion when measuring, scientists use a shared system of measurement, called the International System of Units (SI). ‘Unit’ is the word used to describe how something is measured. When researching a question in science, we collect data, interpret it, and share the results with other scientists.
What is the importance of measurement in baking?
It’s important to have accurate measurements when you bake. One of these kitchen supplies isn’t acceptable for both water and flour. While it’s easy to pour a liquid up to the correct measurement line, it’s much more difficult to accurately pour a dry ingredient into said cup. Scoops are much more accurate.
