Best Answer

Prefixes are symbols that are added before a unit to denote a multiple or fraction of that unit, such as kilo for a thousand or milli for a thousandth. Base units are fundamental units of measurement that are used as a reference for other units in a particular system, such as the meter for length or the kilogram for mass in the metric system.

What are the divisions of metric system?

For units larger or smaller than the base units, you can use prefixes such as kilo (x 1000), Mega (x 1 million), milli (x 0.001), micro (x 0.000 001), etc.; for a complete list, search the Wikipedia for "SI prefixes".


What is the metric system based on mathematically?

The metric system, in mathematical terms, is a base 10 system. This means that the prefixes of the units change the value of the units by factors of 10. For example: 1 centimeter = 10 millimeters.


What matric prefix is used to designate 1000?

The metric system uses differing prefixes to show multiples of ten for base units. To indicate one thousand units, the prefix kilo- is used, as in kilometer, or kilowatt.


What units do scientists use to measure?

Most scientists use the SI, or international standard, system. This includes units and prefixes. The units can be expanded into base (or original) and derived (made from the base) units. The prefixes include centi- (.01), milli- (.001), kilo (1000), and many others. The base units include meters (length or distance), kilograms (mass), and seconds (time), while derived units include liters (Volume), meters per second (speed), and meters per square seconds(accelleration)


What is the base unit for length in the System International Units are called?

Meter. Usually notated as a small "m". Examples: 100m, 0.01m Prefixes that increase the base unit are usually capitalized while prefixes that decrease the base unit are small. Examples: Kilometer (1,000m) = 1Km, Centimeter (.01m) = 1cm


What are the basic prefixs used in the metric system and how do they relate to the size of the base unit?

There are six basic prefixes used in the metric system, and they all relate to the base unit in powers of ten. The smallest, milli, is .001 unit. Next, centi- is .01 units, and deci- is .1 units. The larger units start with deca-, which is 10 units, followed by hecta-, which is 100, and kilo-, which is 1000 units.


What units measure time in the metric system?

The base unit of time is the second. The normal prefixes apply, but miutes and hours are still used.


How do prefixes change the base word?

by making the base word longer


List three sets of base and height measurements for triangles with areas of 30 square units?

The area of a triangle is half base times height so any triangles whose base times height is 60 units will have an area of 30 square units e.g. base = 10 units, height = 6 units; base = 5 units, height = 12 units; base = 7.5 units, height = 8 units.


What are the fundamental and derived units?

In a system of units such as the SI, BASE UNITS are defined; other units are derived from those.For example, in the SI, the meter, the kilogram, and the second are base units; the units for area (meters squared), for speed and velocity (meters/second), etc. are derived from the base units. Which units are base units, and which units are derived units, really depends on how the unit is defined. For example, in the SI, pressure is a derived unit; but you can just as well invent a system in which pressure is a base unit, and some other units, that are base units in the SI, are derived in this new system.


Differentiate derived units from supplementary units?

suplementary units are dimendionless and are not derived from other (base) units while derived units are derived from base units and they do have dimionsions.


Is femo a si prefix?

No, "femo" is not a SI prefix. The SI (International System of Units) prefixes are used to denote multiples or fractions of base units in the metric system, such as kilo-, mega-, milli-, etc.
