## Is cubic centimeter a derived unit?

Since volume is length cubed, its SI derived unit is m3. Related units are the cubic centimeter (cm3) and the cubic decimeter (dm3). Another common unit of volume is the liter (L).

## Which unit is a derived unit?

A derived unit is a unit that results from a mathematical combination of SI base units. Calculations involving derived units follow the same principles as other unit conversion calculations.

## Why is m3 a derived unit?

Answer: From the base unit of length, we can define volume, and from the base units of length, mass, and time, we can define energy. Since volume is length cubed, its SI derived unit is m3.

## Which is a base unit?

: one of a set of fundamental units in a system of measurement that is based on a natural phenomenon or established standard and from which other units may be derived The base units of the International System of Units are the meter, kilogram, second, ampere, kelvin, mole, and candela.

## Is kJ an SI unit?

A kilojoule is a unit of energy in the International System of Units (SI). The symbol for kilojoule is kJ.

## Is kJ smaller than J?

Is Kilojoule bigger than joules? 1 Kilojoule is equal to 1000 joules (J). To convert kilojoules to joules, multiply thekilojoule value by 1000. Kilojoule is a metric systemunit (electrical, mechanical or thermal) and is equal to1000 times of the amount of work done by a force of one newton tomove an object one meter.

## What is kJ per kg?

A kilojoule per kilogram (kJ/kg) is a decimal multiple of the SI-derived unit of specific energy, heating value, energy content, or heat of combustion per unit mass joule per kilogram. The joule per kilogram is equal to the useful energy released from one kilogram of fuel mass during its complete combustion.

## What is Watt formula?

The formula for calculating wattage is: W (joules per second) = V (joules per coulomb) x A (coulombs per second) where W is watts, V is volts, and A is amperes of current. In practical terms, wattage is the power produced or used per second. For example, a 60-watt light bulb uses 60 joules per second.
