we answer quantities precisely by using measuring tools like rulers, and meter sticks :)
The ISO standard units of measurement.
You can measure flour in kilograms, or (for smaller quantities, typical for recipes) in grams.You can measure flour in kilograms, or (for smaller quantities, typical for recipes) in grams.You can measure flour in kilograms, or (for smaller quantities, typical for recipes) in grams.You can measure flour in kilograms, or (for smaller quantities, typical for recipes) in grams.

The uncertainty principle in quantum physics says that there is a limit to how precisely you can measure one of a pair of variables like position and momentum. You can measure position precisely, but you cannot at the same time precisely measure momentum. Or . . . you can precisely measure momentum, but you cannot at the same time precisely measure position.
You cannot.Miles per hour is a measure of speed, with dimensions [LT^-1] whereas Hertz is a measure of frequency, with dimensions [T^-1]. According to the very basic rules of dimensional analyses, conversion between the two is not valid.
There is no sensible answer to this question. A knot is a measure of speed, with dimensions [LT-1]. A mile is a measure of distance, with dimensions [L]. Basic dimensional analysis teaches that you cannot convert between measures with different dimensions without additional information.
Qsurveyit.com has a very easy system for this. Enter your patio dimensions and it'll tell you all of the material quantities
3cm is a measure of distance, with dimension [L]. Density is a measure of denseness (as the name suggests) with dimensions [ML-3]. Basic dimensional analysis teaches that you cannot relate quantities with such diverse dimensions without additional information.
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
how primitive people measure quantities
No
You take a ruler or tape measure and measure the dimensions you need.
Use a graduated cylinder to precisely measure volume
Yes.
Small quantities are measured in millimeters. Millimeters is used to measure small quantities.
With a tape measure
The answer will depend on (a) whet the dimensions of the two quantities are, and (b) what the missing operator between the two quantities is.
All physical quantities are combinations of one or more of the dimensions of length, mass, time, and electric charge.
