Everything You Should Know About a Unit Converter

A unit converter is a tool that helps you convert between different units of measurement. These conversions are essential for scientific work in chemistry or engineering.

In chemistry, maths, or engineering, converting between units is a crucial part of dimensional analysis, which measures and transforms quantities. To do so, you need to know what units are used, how they are converted, and how to apply conversion factors.

 

This article gives you a brief idea of everything you should know about units.


Units of Measurement

A unit of measurement is defined as a definite magnitude of a particular physical quantity, generally adopted as a standard for that particular kind of measurement. Any other quantity of that same kind may be expressed as a unit of multiple.

 

A meter (symbol m) is a unit of length representing a definite predetermined length. Various units of measurement are used to express length including the meter, centimeter, inch, and foot.

The area is another category of measurement using units of length, but they are not the same. For example, a square foot is an English unit of measurement equivalent to a square with sides 1 ft each, while a square meter is a metric unit of measurement corresponding to a cube with sides 1 cm each.

 

The purpose of unit conversion is to change the values of the original measurement to something meaningful in a different system of units. This can be done through several conversion factors that cancel out the old units and introduce the new ones.

Conversion Factors

Conversion factors are a type of math that most people are familiar with and use daily. They allow for conversions between different units of measurement and make it easier to convert one set of numbers into another.

 

Essentially, these factors represent ratios that express the same property in different units. So, for example, you may need to convert feet into cms to measure the length of a chain or to convert inches into millimeters for a certain measurement.

 

To solve a unit conversion, multiply or divide by the factor and round off the results. This process can be complicated if you don’t know what you’re doing or don’t have the correct unit conversion factor. Check out here to know more.


Metric Units

Metric units are a set of basic measurements adopted internationally and are now used by most countries. The meter (m) is the unit of length, the kilogram (kg) is the unit of mass, and the liter (l) is unit of volume.

 

Metric systems use a system of base units based on ten and are, therefore, easy to understand. These base units include meter (abbreviated m), gram (g), and liter (abbreviated l).

 

In the metric system, a kilometer is one thousand meters, a kilogram is one thousand grams, and a liter is one thousand liters. These units are the basis of all other derived units.

 

The metric system is an international decimal system of weights and measures based on meter and kilogram, which was adopted in France in 1795. Since 1875, the International Bureau of Weights and Measures has been established in Sevres, near Paris, to maintain and improve the metric system.

US Customary Units

US Customary Units are a system of weights and measures used in the United States. It is similar to the imperial system developed in Britain but with some differences.

 

The customary system is based on the yard as a unit of length, the pound as a unit of weight, the gallon as a unit of volume, and the bushel as a unit of dry volume.



Throughout the world, customary units have been developed and adopted. Some are derived from the same English units the US Customary System is based on, while others have roots in Roman or Anglo-Saxon measurements.

 

When converted to unit conversion, the US Customary units will become the equivalent of the metric units. This is because the metric system is a decimal system with prefixes that correspond to a power of ten.
