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.

Must two quantities have the same dimensions when subtracting them?
Yes they must be in the same units of measurements.
Is this true that conversion factor is a ratio of equivalent values used to express the same units in different quantities?
No. The same quantities in different units.
Must quantities have different units before they can be added or subtracted?
no
What is a ratio that compares two quantities that are measured in different units?
what is it
What is a fraction that compares two quantities measured in different units?
A rate is a fraction that compares two quantities measured in different units. If the denominator of the fraction is 1 unit, the rate is called a unit rate.
Must two quantities have the same dimensions?
If you intend 'dimensions' to mean units then whenever the two quantities are to be operated on each other then they must have the 'dimensions', refer to dimensional analysis
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.
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.
Is it true that two quantities having the same dimensions must be measured in the same units?
No, it is not true.
Must two quantities have the same dimensions when subtracting them?
Yes they must be in the same units of measurements.
Is this true that conversion factor is a ratio of equivalent values used to express the same units in different quantities?
No. The same quantities in different units.
How do you measure quantities or dimensions precisely?
we answer quantities precisely by using measuring tools like rulers, and meter sticks :)
Ratio that compares 2 quantities measured in different units?
ratio that compares 2 quantities measured in diiferent units
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 a comparison of two quantities with different units?
ratios
A ratio that compares quantities of different units?
rate
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.
