What word means the use of units to find a size of quantity?
To measure, or measuring is the use of units to find a size of quantity
What units are used to measured heat quantity?
Heat quantity is measured by 3 different types of units. In the united states, Fahrenheit is the standard measurement. We also use Celsius. There is one more besides these two and it is Kelvin.
Why do we have different units for same physical quantity?
There are a few reasons. Historical and cultural: different units were used at in different parts of the world at different times. Many of these "traditional" units were eventually replaced by the SI system. However, even within the SI system, there are different units which are appropriate at different orders of magnitude. For example, the metre is the standard unit for length but it is not the most sensible unit for atomic distances, nor is it appropriate for distances between cities. Furthermore, in astronomy or cosmology there are other units such as an astronomical unit (AU = average distance between the earth and sun), a light year (the distance travelled by light, through vacuum, in one year), a parsec (the distance at which a star appears to be displace by one second of arc between the two extreme positions in the earth's orbit).
Where to get answers for science dimensions 1?
If you wish to know about the names and types of science dimensions, then have a crack at SI Units in Wikipedia.org
Convert ohms to Fahrenheit?
"Ohm" is a unit of electrical resistance, whereas "Fahrenheit" is one of many scales widely used for the description of temperature. It is difficult to think of two units that could be any less alike in definition, dimensions, or application. In any case, the two units have different 'dimensions' and are used to measure different quantities. There is no way that either one of them can be converted into the other one.
Can a quantity have unit and still be diamensionless?
No, a quantity cannot have units and still be dimensionless. The dimensions of a quantity are determined by its units, so if a quantity has units, it has dimensions. Dimensionless quantities are those without any units.
Why are several units associated with the same physical quantity?
Multiple units may be associated with the same physical quantity due to historical reasons (different regions developing their own units) or different systems of measurement (metric vs imperial). In some cases, units may be related by simple conversion factors, allowing for flexibility in expressing measurements.
If all the terms in an equation have same units then is it necessary that they have same dimensions?
if they have same units they must have same dimensions . but thy can have different units even if they have same dimensions i hope it helps :
Can a quantity be dimensionless and have no units?
Yes, a dimensionless quantity is a quantity that does not have any physical dimensions or units. It is a pure number or ratio that represents a comparison between two quantities. Examples of dimensionless quantities include angles, ratios, and pure numbers like pi.
What is the SI unit fro expressing the quantity?
There are different units for different quantities.
What is dimensions of physical quantity?
Physical quantities can have dimensions, which represent how they are measured or expressed in terms of fundamental units like length, mass, time, etc. These dimensions help in defining and comparing different physical quantities. For example, the dimension of speed is [Length] / [Time] as it is defined as the distance traveled per unit time.
What are the dimensions of magnetic field?
The dimensions of magnetic field are given in units of Tesla (T), which is equivalent to kg/s^2A. Magnetic field is a vector quantity with both magnitude and direction.
What are the different types of air conditioning units available in the market?
The different types of air conditioning units available in the market include window units, portable units, split systems, central air conditioning systems, and ductless mini-split systems.
What is the different between international system of units and significant digits?
They are totally separate things. Systems of units are standard sets of dimensions in which things are counted and measured. Significant digits are simply accuracy levels in numbers, such as 3.142 compared to 3.1416.
Can a quantity have units but still be dimensionless?
No. "Dimensionless" means there are NO units involved.
What happens to units when you take the logarithm of a quantity?
When you take the logarithm of a quantity, the units of the quantity are removed.
Is size a quantity?
Size is a measurable quantity that represents the dimensions or extent of an object or space in physical terms. It is typically measured using standard units such as length, width, height, volume, or area.
