Measurement provides a standard for everyday things and processes. From weight, temperature, length and time, it has served humanity from ancient times. It helps the 21st Century people to understand what ways our ancestors were combating the daily struggles of life when it comes to precisions and numerical values as we know them today. How the bartering system was changed to a monetary conversion system, how human body parts used for measurements were overtaken by the modern-day rulers and how shadows to measure time were surpassed by the digital and analog clocks.

Modern unit conversion calculators are proved to be extremely pivotal. Unique algorithms have developed powerful online unit converter utilities that will help make easy conversions between various units of measure in 12 categories. Our unit converter converts everything from length and force to flow and temperature. It comes with customized features for increased functionality. In case the user may find it difficult finding the value in a specific unit converter, there is a complete description for each unit, the uses of it and how to efficiently use it online for free. All the tools and groups are carefully studied and used as per scientifically defined standards set for the groups as scales of the measurements and are internationally agreed.

The output value box of the program gives one-to-one conversions of the units you select. The following groups can be converted without any hassle:

Length Converter, Temperature Converter, Time Converter, Area Converter, Weight Converter, Bits/Bytes Converter, Torque Converter, Power Converter, Pressure & Stress Converter, Velocity & Speed Converter, Volume & Capacity Converter, Electricity/Voltage Converter

Engineers depend heavily on the judgment by the unit converters. They need precise conversions for a specific situation and the intended purposes. The numbers with significant figures of the measurement are also considered for the exact details.

Occasionally, **Soft Conversions** are used. These are conversions from one system of units to another, need to be exact without the decimal values. For example, if we convert 1 Foot (ft) into Centimeters (cm), the answer will be rounded up to 30 cm in soft conversion units. However, in the **Hard Conversion**, the values after the point will also be considered that would be 30.48 cm.

Scientists have been using multiple devices over time to measure the temperature, but the most commonly used tool is Thermometer. A thermometer has two main functions to carry out. It consists of a sensor that records the changes in the temperature, and the other sensor shows the result into a numerical value. The principal objective of this device is to record the cold and hot. There are thermometers to check how hot an oven is before baking and while cooking, there are thermometers available to monitor the temperature of the body and even the air temperature measurers.

There are four big temperature measurement units to find about the temperature. The classic English system of measuring temperature Fahrenheit signifies that water freezes at 32 degrees Fahrenheit and boils at 212 degrees. This temperature unit that is most commonly used is Celsius which is based on the temperature of water. It identifies 0 Degree Celsius as a freezing point and 100 Degree Celsius as the boiling point. In the field of temperature measurement, Lord Kelvin has numerous contributions; therefore, another unit to measure temperature mostly used in science is Kelvin which is based on a single point, absolute zero, which has been given a value of 0 degrees. While not much widely used but a vital unit to measure the temperature is Rankine that the US engineering field uses. Rankine scale distinguishes an absolute Zero Degree based outcome.

Time is defined as a one-dimensional element to segregate and quantify the events that have happened in the past; the events that are happening. It is also used to measure the motions of objects.

Time is referred to as 24-hour span of a day. This valuable element revolves everything around it as the working of the day is dependent on it. The time we get up, the work timings we have, meetings on time and even our sleep patterns are reliant on it. The time converter let the user use the option of international time converter, to compare time zones and can also be used to check the world clock times and converted them. The tool also has the feature of converting Years to Centuries and also has the additional features of Sidereal and Mean Solar days, hour and minutes.

Length and distance measurement might seem to perform the same function, but that’s not the case. Length describes how long is the dimension of an object is whereas the distance is the measurement of how far the objects are from each other. In the international system of unit, SI, the basic unit to measure the distance and the length is a meter. This metric system has to measure units that include kilometers and centimeters. Other commonly used groups of length are the inch, the foot, the yard, and the mile. It is also to be noted that the distance value can never be in negative and always has a scalar value. When it comes to calculating the distance of a circular object, it is converted using the radius of the field.
