Is femo a si prefix?
no; however, femto- is an SI prefix meaning 10-15
What are prefixes and base units?
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 does these prefixes for deca?
The prefixes for deca indicate a factor of ten. For example, "deca-" represents 10, "hecto-" represents 100, and "kilo-" represents 1,000. These prefixes are commonly used in the metric system for units of measurement.
List SI units of measurements and common SI prefixes?
SI units of measurements: meter (length), kilogram (mass), second (time), ampere (electric current), kelvin (temperature), mole (amount of substance), candela (luminous intensity). Common SI prefixes: kilo- (k, 10^3), mega- (M, 10^6), giga- (G, 10^9), milli- (m, 10^-3), micro- (μ, 10^-6), nano- (n, 10^-9), pico- (p, 10^-12).
How do the prefixes in the metric system to the basic unit?
In the metric system, the base units relate to the dimension being measured: kilogram for mass, meter for length, second for time, ampere for electric current, and a few others. (see related link) The liter is not an official SI unit but is commonly accepted as a unit of volume. The prefixes represent a power of ten that is multiplied to give a unit of a certain value. See the related link for a table of prefixes. Some examples are kilo- (meaning 1000) gives kilometer (1000 meters) and kilogram (1000 grams). Milli- (derived from the Latin word for 1000, but meaning 1/1000 or 0.001); therefore, milligram is 0.001 grams, millimeter is 0.001 meters, milliliter is 0.001 liters, and millisecond is 0.001 seconds. Any of the prefixes can be used with a unit, but some are more commonly used than others. Prefixes can also be used with derived units which have special names. For example: kilowatt, kilopascal.

Why are prefixes useful when describing SI units?
Prefixes are useful when describing SI units because they allow for easy conversion between different units of measurement by indicating a multiple or fraction of the base unit. This helps to express quantities in a more manageable and standardized way.
What unit of force is smaller than the newton?
In the SI, the usual SI prefixes would be used for smaller units - prefixes such as milli, micro, etc.
Which SI units can be used to describe the measurment of volume?
The SI unit for volume is the cubic meter (m^3), but for smaller volumes, the liter (L) is often used.
What measure is volume in units?
milliliters, deciliters, litersAnswer:The official SI unit for volume is the cubic meter. Surprisingly, the liter is not the official SI unit of volume, although is is commonly accepted as such and used with metric prefixes.
What do you call the principal SI units that are used to derive all other SI units?
The principal SI units used to derive all other SI units are the base SI units. These are the units for physical quantities such as length, time, mass, electric current, temperature, amount of substance, and luminous intensity.
What are SI units used for?
they are units for scientist
Is feet an SI unit?
No. The SI unit of length is the meter; the same unit with prefixes (such as millimeter and kilometer) is also used.
How do you define the unit prefixes Tera Giga Mega kilo hecto deca?
Tera represents 10^12, giga represents 10^9, mega represents 10^6, kilo represents 10^3, hecto represents 10^2, and deca represents 10. These prefixes are used to indicate multiples of 10 in the International System of Units (SI).
When SI units combine what do they make?
When SI units combine, they create derived SI units that are used to express physical quantities. These derived units are formed by multiplying or dividing the base SI units. Examples include the Newton (kg*m/s^2) for force and the Pascal (N/m^2) for pressure.
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".
Explain why prefixes are useful with SI units?
Sometimes you need a very large, or a very small, amount of a certain unit. One way to deal with that is to use prefixes like kilo, mega, milli, micro, and others.
