Short Desciption:
Type in unit symbols, abbreviations, or full names for units of length, area, mass, pressure, and other types. Examples include mm, inch, 70 kg, 150 lbs, US fluid ounce, 6′3″, 10 stone 4, cubic cm, metres squared, grams, moles, feet per second, and many more. Metric, british/american, avoirdupois systems, but also more exotic systems like japanese, ancient greek, biblical and old swedish measures. Below and in the navigation menu on the left you can find the different measurements to convert. Area Conversion In this category you can find the following measurements. Interactive calculator used to convert between various units of measurement. Area, volume, length/distance, cooking, time, and more. Online weights and measures conversion. Online calculators for quick and easy metric conversion, conversion tables for both commonly used and very exotic units.

KMS stands for kilogram, meter, second. We will learn many other KMS quantities during the course. At this time students should be familiar with the following measurements. Variable Variable Symbol Definition KMS Unit Unit Symbol mass m Quantity of matter kilogram kg distance d Total path length meter m displacement x Straight line distance meter m time t Difficult to define second S temperature T Relative hot and cold Kelvin K Many of the other measurements and units are derived from these. As an example: speed is distance divided by time and has the units m/s. These are the agreed upon units that are used in Physics calculations. Therefore, students must learn how to convert other units of mass, distance, and time to these. The equations in physics depend on unit agreement. You must convert to KMS units in order to get answers that agree with those of others. The following conversions will be provided in a table of information used during all tests including the AP exam. Now is the time to master conversions so that the entire year is easier. Using the table to get base units is easy. Simply replace the symbol with the factor in the table. Some examples are shown below. Converting from base units to other units requires you to divide by the factor. This is most frequently done from grams to kilograms, which is the only unit used in Physics that is not plugged into equations in base unit form. The more difficult conversion is from base units to a prefix unit. In Physics, the most common conversion of this type is grams to kilograms. Don’t let the symbol µ confuse you. It is a Greek letter and stands for micro. Just learn to recognize it and write it like any other letter. All physical quantities have units so that we can communicate their measurement. In the metric system, the base units are called SI units. The base SI units for the fundamental quantities as talk about above. Any unit which is a combination of these fundamental units is called a derived unit. An example of a derived unit would be meter/second or kilometer/hour, which are both units of speed. Sometimes we will need to convert from one unit to another.
