Kilo prefix

The CIPM has approved twenty prefixes for SI units (see Table 3) and permits the use of any SI prefix with an SI unit, with one exception. The SI unit for mass, the kilogram, already has a prefix in its name and can have no other SI prefix. To use prefixes with a unit for mass, the rule is to remove the kilo prefix and add the new prefix to gram (unit symbol g), as in milligram and its abbreviation mg.

Larger and smaller distances may be measured with units formed by the addition of prefixes to the word meter. The important metric prefixes are listed in Table 2-2. The most important prefixes are kilo, milli, and centi. The prefix kilo means 1000 times the basic unit, no matter to which basic unit it is attached. For example, a kilodollar is 1000. The prefix milli indicates one-thousandth of the basic unit. Thus, 1 millimeter is 0.001 meter 1 mm = 0.001 m. The prefix centi means one-hundredth. A centidollar is one cent the name for this unit of money comes from the same source as the metric prefix.

The most common prefixes used in medicine are kilo, which is 1,000 times the base unit, centi, which is 1/100 of the base unit, and milli, which is 1/1,000 times the base unit. These prefixes are attached to the base unit to give the multiple of the base unit being measured. Therefore, a kilogram is 1,000 grams. A centimeter is 1/100 of a meter. A milliliter is 1/1,000 of a liter. 

SI base units include the meter (m), kilogram (kg), second (s), ampere (A), kelvin (K), and mole (mol). Derived quantities such as force (newton, N), pressure (pascal. Pa), and energy (joule, J) can be expressed in terms of base units. In calculations, units should be carried along with the numbers. Prefixes such as kilo- and milli- are used to denote multiples of units. Common expressions of concentration are molarity (moles of solute per liter of solution), molality (moles of solute per kilogram of solvent), formal concentration... 

One major advantage of the metric system is that it uses a decimal system, which means all units are related to smaller or larger units by a factor of 10. Some of the more commonly used prefixes along with their decimal equivalents are shown in Table 1.2. From this table, you can see that 1 kilometer is equal to 1000 meters, where the prefix kilo- indicates 1000. Likewise, 1 millimeter is equal to 0.001 meter, where the prefix milli- indicates Xooo- You need not memorize this table, but you will find it a useful reference when you come across these prefixes in your course of study. 

B 103, a thousand, is the value that is represented by the prefix kilo-. 

The prefix kilo- means 1000 times the primary unit, no matter which primary unit it is used with. For example, a kilogram (kg) is 1000 g, and a kilometer (km) is 1000 m. 

The metric system problem, part (a), can be solved without paper and pencil— by moving the decimal point in 5.200 three places to the right. The English system conversion, part (b), requires that we remember the number of yards per mile (harder than the 1000 m/km metric conversion factor) and that we use pencil and paper or a calculator to do the arithmetic. The conversion factor 1000 is used for kilograms, kilohters, kilowatts, and any other factor involving the prefix kilo-. The English conversion factor 1760 yd/mile is not used in any other conversion. 

The prefix kilo- means 1000 of whatever it is attached to. Therefore, 1 kg is... 

The metric system and its newer counterpart, SI, use subunits and multiples of units that are equal to powers of 10, and they also use the same prefixes to mean certain fractions or multiples, no matter what primary unit is being modified. The meter is the primary unit of length the gram is the primary unit of mass and the liter (the cubic meter in SI) is the primary unit of volume. The prefixes centi-(0.01), (0.001), and kilo (1000) are used with any of...
