(If the original measurement has the given units in the numerator, the conversion fraction needs them in the denominator, and vice versa.) And when a fraction has the same numerator (top number) and denominator (bottom number), that fraction equals 1. To convert from one unit to another, you either divide or multiply, depending on whether you are converting a smaller unit to a larger one, or a larger unit or to a smaller one.

Causey also shares the major prefixes and their meanings. With the global flow of information that occurs these days, it is very important for students to learn these most basic conversion factors. We have prepared an Excel Unit Converter Template to consolidate all necessary conversion units into one tool. A conversion factor is used to change the units of a measured quantity without changing its value. Knowing the units of measurement that correspond with a number can give you so much more information than a digit sitting there by itself. It is one of the most widely used converters in Physics which mostly involves the energy. metric or standard). The basic Metric Conversion Chart Templates is the beginner’s guideline to refer to a table to convert the basic units of measurement such as length, volume, distance, time, speed and temperature. If you are not aware of that topics consider first reading my complete article about the measurement of physical quantities. The importance of units and iteration in measurement In order to become proficient in measuring space (in terms of length, area or volume), children need to understand two fundamental concepts: the idea of a unit and the process of iterating a unit to complete a measurement.
