A system of measurement is a collection of units of measurement and rules relating them to each other.

We have two types of systems of measurement:

The Metric System, adopted in France in 1795, is a system of measurement that is now used officially in almost all countries. After the French Revolution, the government decided to have one standard system of measurement to unify the whole country. Since then, 'The Metric System', also called SI, has been the universal measurement system for nearly all countries except the USA.

The Imperial System of Units (also called imperial system or imperial units or British Imperial) was a system of measurement that was mainly used by countries like the UK, Canada, New Zealand, Australia, USA, etc. However, the only country that currently uses this system for measurement is the USA. It is based on feet, inches, pounds, and Fahrenheit.

All three-dimensional objects occupy a space, we measure this space using units of 'volume'. Volume is the space occupied by an object in three-dimensional space. It is used to measure solids and liquids.

Weight measures the heaviness of objects, which can be food, a ball, human weight, etc. Let's see which units are used to measure weight in the imperial (US) and metric systems.

The area of an object can be measured from several aspects. Length typically refers to the longest side or the distance between two points. Width refers to the horizontal dimension, while height refers to the vertical dimension. Finally, depth is the distance from the surface to the farthest point.
In the Imperial System, measurements of area are typically expressed in units such as inches, feet, miles, and acres.

When we want to talk about temperature, we must know that there are differences between they way the world analyzes it and the way Americans do it. We mainly use Celsius whereas, Fahrenheit is used among Americans. The difference between them is that the Celsius scale, or Centigrade scale, is based on water freezing at 0°C and boiling at 100°C. On the Fahrenheit scale, however, water freezes at 32°F and boils at 212°F. Look at the formula below:

By using the formula above, we can easily convert Celsius degrees to Fahrenheit.

When cooking, you might face different measurement units. Let's go through some of them:

There are some expressions you might face in the cooking books, here we have explained some of them:

The ingredient is pushed lightly into the measuring device, only tightly enough to make sure no air pockets.

With a spoon, or by hand, the ingredient is pushed as tightly as possible into the measuring device.

A precise measure of an ingredient, get rid of all of the ingredients that rise above the rim of the measuring device. Sweeping across the top of the measure using the back of a knife or something like that is a common leveling method.

The highest amount of an ingredient that will stay on the measuring device.

Letting a measure of an ingredient accumulate above the rim of the measuring device by itself, into a soft, rounded shape.
