What are all SI units?]
What else can I help you with?
What is the base unit of mass?
The mass is obviously a base unit. From mass we can derive many units like momentum, force etc. But we cannot derive the unit of mass from any other unit. So, it's a base unit. Technically, mass is not a unit. In the most commonly used systems of units, MKS and cgs, units of mass (kilograms and grams, respectively), are base units.
Is the centigram the base unit for mass?
No, the centigram is not the base unit for mass. The base unit for mass in the International System of Units (SI) is the kilogram. The centigram is a subunit of the gram, which is derived from the base unit of mass.
Is coulomb an S I base unit?
No, a coulomb is a derived unit. A base unit is a unit that isn't made by combining other units. There are seven base units, including metre (length), kilogram (mass), and second (time). Coulomb is the unit of electric charge. One coulomb is the charge delivered by a steady current one ampere in one second. It is derived from the base units ampere (electric current) and second (time).
Why the unit of density is called derived unit?
Density is not a derived unit.. It is a physical quantity and hence is a derived quantity.. the unit of density kgm-3 or gcm-3 is a derived unit because it can be expressed as the quotient of base units. In general, a unit is said to be derived if it can be expressed as the product and/or quotient of base units.
What is the SI unit of measurement used to express pressure?
The SI unit for pressure is not a base unit, it is a derived unit. The SI derived unit for stress is the pascal (Pa). 1Pa = 1N/m2 or 1kg/m∙s2, which means one Newton per meter squared, or one kilogram per meter times second squared. NOTE: The 2 should be a superscript.
What is the difference between base unit and a derived united?
A base unitis a defined unit in a system of measurement that is based on an object or event in the physical world.A derived unit is a unit that is defined by a combination of base units.
Is the unit for force a base unit or a derived unit?
The unit for force, the newton (N), is a derived unit in the International System of Units (SI). It is derived from the base units of mass, length, and time.
Is the cubic centimeter a base or derived unit?
yes, cubic centimeter is a derived unit.
When you multiply measurements you make a derived unit?
In some cases, multiplying measurements can result in a derived unit. Derived units are created by combining base units in a specific way, such as meters (a base unit) multiplied by seconds (another base unit) resulting in meters per second (a derived unit for speed).
Is grams a base unit or a derived unit?
Grams is a derived unit because it is based on the base unit of mass, which is the kilogram. It is a smaller unit of mass that is derived from the kilogram through the use of prefixes such as milli- and micro-.
Is meters per second a base unit?
No, it is a derived unit.
What is the difference between a base unit from a derived unit?
There are 7 base SI units and all other are defined using these 7 base units. See the related question below:[http://wiki.answers.com/Q/What_are_all_the_SI_unitsWhat are all SI units?]

What is the Si base unit for energy?
There is no SI Base Unit for energy. The unit for energy, the joule is a Derived Unit.
Is the unit for density a derived unit or a base unit?
That will obviously depend on the system of units chosen. In the SI (International System), it is a derived unit (mass divided by volume).
What is the metric base units of volume?
The meter is the metric base unit for volume, and the cubic meter is the derived unit.
Why ampere is base unit if it is derived from charge?
The ampere is the SI Base Unit or electric current. It is NOT derived from the charge (coulomb) but from the force resulting from its magnetic effect. The ampere is defined in terms of the force between two, parallel, current-carrying conductors due to the interaction of their magnetic fields. The coulomb, on the other hand, is an SI Derived Unit, based on the ampere and the second.
