Relative intensity is measured in decibels and is abbreviated dB.
Relative density, is also called specific gravity, and it is the ratio of the density (mass/volume) of a substance to the density of a particular reference substance, usually water. So, where density has the units of mass/volume, relative density (specific gravity) is unitless.
comparative scale is a pair of scales having a common R.F. but graduated to read different units. A map drawn with a scale reading miles and furlongs can be measured off directly in kilometre and hectometre by a comparative scale.
UNITS
There is no abbreviation for metric, but there are "metric symbols". Here are the SI Basic Units: We use 7 SI Basic Units. They are: Quantity, Name, and Metric Symbol length meter m mass kilogram kg time second s electric current Ampere A thermo dynamic temperature Kelvin K amount of substance mole mol luminous intensity candela CD

Intensity
Intensity can be measured by converting units of electrical power in to decibels.
Sound intensity I is measured in watts per meter squared (W/m²). Look at the link: "Conversion of sound units (levels)".
Light bulb are measured in Candela (Cd) for its luminous intensity and Watt for its power consumed.
Sound is measured in dB ( Decibels) for intensity and or Hz ( Hertz) for frequency or pitch.
Atomic radius is measured in picometres; 1 pm = 10e-12 m.
Pressure is defined as Force per Unit of Area. In the Imperial system of units it is usually measured in Pound per Squre Inch, abbreviated to P.S.I.. In the metric system it is usually measured using the units :- KiloPascal abbreviated to kPa. Car tyre pressure is always expressed in either of these units I have named. A 'Pascal' is defined as 1Newton per Square Metre. A KiloPascal is equal to 1000 Pascal. A Newton is a unit of Force, not, a unit of Pressure. 1Newton = 0.102 Kilogram force.
Because a perimeter is measured in linear units while an area is measured in square units.
No, volume is measured in cubic units, area is measured in square units.
Sound intensity is measured in watts per square meters, but our eardrums are only moved by the sound pressure measured in newtons per square meters or pascals.
