What Is a Unit Converter?

In everyday activities, we interact with many forms of measurements. That is why we need a unit converter to help is in calculations. Since everything has a value, people have devised a way of quantifying them to meet monetary or quality specifications. This quantification process is done in units. Therefore, a unit is the measure of quantity to give value to matter. 

Before civilisation, each community, kingdom, empire, or chiefdom had its measure of value for its goods. However, with technological advancement and unification through science, governments decided to create a cross border unit of measurement. This is how the International System of Units (SI Units) was formulated. Its standardization process is adopted throughout the world for unification, and the units of measurement are incorporated in the laws of the land.

Different Countries Have Different Units of Measurements​

Countries have their systems of measurements, owing to their allegiance and scientific research. Their systems resonate with their environment. Some first world countries have adopted newer measurement options that suit their demand. Below are some of the units of measurements and where they are used:

  • Weight: The SI unit of weight is in Newton (n). However, British Engineering measure weight in pound-force (lbf)
  • Mass: Most English speaking countries' measure of mass is in grams (g). The United States measures mass in pounds.
  • Length: America measures length in terms of yards (yd) and miles (mi) while other countries prefer metres (m) and kilometres (km)
  • Area: Countries that use metres as units of measuring length adopts metres square (m²) as their area unit. The Americans have adopted square foot (ft²) to measure their area.
  • Temperature: Americans use degrees Fahrenheit (ºF) to measure temperature while others use Degrees Celsius (ºC).

How Does Unit Converters Work?

Unit converters use regulations, specifications, and internationally accredited standards. The aim is to:

  • Ensure accuracy: The uncertainty of matter invokes accuracy in measurements.
  • Confidence level in analysis: Getting the right measurements leads to accurate inferences.
  • Equivalence amongst different measurement levels: Territories that use different SI units can find equivalents in their units.
  • Precision science: Gets the right measurements for engineering purposes.

Unit converters used in software such as calculators, applications, spreadsheets, and computer plugins have inbuilt algorithms. The binary figures are formulated to precision to give the most accurate estimations. Below are some of the unit conversion equivalents used globally:

1 foot = 0.0001893939 miles

1 centimetre = 0.3937007874 inches.

1 foot = 0.3048 meters

1 degree Celsius = 33.8 degrees Fahrenheit

1 metric horsepower = 735.49875 Watts

Basic unit conversion works through comparing Units. Units that fall in the same bracket have a standard measure. If they are compared to another unit in the same bracket (different SI Unit – imperial vs. metric), the equivalents form the conversion.

Why Use a Unit Converter?

Accurate figures

When working on any arithmetic or estimations, the use of unit converters keeps the answers accurate. This helps especially in engineering and other fields that require precision.


If you decide to use the American standardisation system, unit converters help you get the measurement in one form throughout your work. It makes understanding easier and information relatable.

Right measurement

Whenever you cross into a country that uses different measurement units, the unit converter helps you to get the right equivalent. It helps with the measure of value and efficiency.


Physical eyes or weight cannot give an exact weight or mass of an object or liquid. For commodities which are not from the same cluster but have proportionate measurement method, comparison can be used to get the actual quantity.

Research unification

Research in any science field carried out anywhere in the world can be used if it uses unit convertor. A majority of the countries use the metric system, which unifies all research methodologies and inferences.


Conversions in velocity, speed, and volume flow are useful, especially in estimating distance and time. These estimations can help in solving related calculations. Such actions improve efficiency and planning.

Frequently Ask Questions About Unit Conversions

Which is superior between the metric system and the imperial system?

The battle for superiority between the two does not arise. The imperial system resonates with the people who use it. The same applies to the metric system. The Unit Converter tries to bridge the superiority gaps between the two systems. The composition is the same; hence valuation is the same.

What is the difference between mass and weight?

Mass is the amount of the material in an object or body, while weight is the force the object or body exerts through gravity. Mass is measured in grams, while weight is measured in newton. As long as there is matter, mass can never be zero, but weight can be zero if the object has no gravity.

How accurate is the Writing Tools’ unit converter?

Writing Tools uses unit conversion plugins specifically designed by developers who understand the conversion algorithms. The figures are set to precision, the convertors are tested, and the model ascertained to give the best comparison in the market. There are also other complementary tools such as the article writing services, word to HTML, and character counter, which makes Writing Tools a one-stop-shop for all online technical services.
