How do you find the precision of measurements?
To check the precision of an instrument its apparent measurement must be compared to a known measurement. The difference between the measured quantity divided by the known quantity is expressed as a % precision of the instrument, or calibration. Most instruments when being calibrated are tested against multiple known quantities throughout the range of the instrument. Thus the precision of the instrument is determined throughout it's full range of measurement.

Why does a beam balance measure mass?
Beam balance measure mass by comparing unknown quantity with known standard quantity of mass.Beam balance measure accurate quantity of matter present in that body .Quantity measured by beam balance doesn't differ in any place of world either in poles or equator but measuring scale quantity differ in different places

How is the volume of an irregularly shaped solid measured?
The volume of an irregularly shaped solid can be measured by placing the solid in a known quantity of water in a container with measurement markings. Take the new volume and find the difference between this and the old volume. This is the volume of your irregularly shaped solid.
