Does a quantity have different dimensions in different systems of units?

No. The dimensions are: Mass, Length, Time, and Charge. They transcend the systems of units.
For example, speed will always have the dimensions of (Length)/(Time), regardless of the system
of units.

The implications of an object without dimensions, are that it takes up no space, If an object takes up no space then it doesn't exist. The exception to this rule is light, but light is not a physical quantity.

Not all have spatial dimensions for example mass has no spatial dimension , it's dimension is measured in kilograms.

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.
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 :
What is the SI unit fro expressing the quantity?
There are different units for different quantities.
What do you mean by the term quantity?
quantities which are not mademade from major quantities
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.
What are the dimensions of a rectangle that has a perimeter of 44 units and an area of 105 square units?
The dimensions work out as 7 units and 15 units
What is a ratio of equivalent values used to express the same quantity in different units?

Is it possible for two quantities to have the same dimensions but different units?
No. Measurement units are defined by and conversely. So the same units necessarily means same dimensions.
What are the dimensions of square that has the perimeter and the area equal in value?
The dimensions can be 4 units by 4 units
What is the rectangle dimensions of 7 and 35?
The dimensions are: width of 7 units and length of 35 units!
What is the unit of photometer?
There is no such thing. There are different units, depending on what exactly (what physical quantity) you want to measure.
What are the dimensions of a 34 perimeter and 30 area rectangle?
The dimensions of the rectangle are 2 units and 15 units
Can the perimeter of a shape be greater than its area?
The two are measured in different dimensions of units and are therefore incomparable.
