Mass:- amount of matter in object
=>  1 kg = 1000 gram
Weight: -force on the object by gravity.
Volume:- (length)3
=>  1 L = 1000 ml, 1000 cm3 = 1dm3
Density:- Amount of mass per unit volume.
=>  SI unit :- Kgm-3
Temperature:- It is the measurement of cooling or warming.
Three scales
=>  0C (Degree Celsius)
=>  0F degree Fahrenheit)
=>  k (Kelvin)
=>  freezing point of water = 0 0C
=>  Boiling point of water = 100 0C
Relationship
CHEMISTRY
Or,
k = 0C + 273.15
Precision:- Closeness of various measurement for same quantity.
Accuracy:- It is the agreement of a particular value to the true value of the result.
Significant figure:- The meaningful digits which are known with certainty.
