The results of measurements are quantities
A quantity is expressed as ………
The International System of Units (SI)
The unit of electric current (ampere)
The unit of thermodynamic temperature (kelvin)
The unit of amount of substance (mole)
The unit of luminous intensity (candela)
Non-SI units accepted for use with SI
Multiples and sub-multiples: the SI prefixes
Does it matter if you don’t use SI units?
And now what about the numbers?
And now what about the numbers?
The correct expression of numbers
The expression of measurement uncertainty
The expression of measurement uncertainty
Reporting the measurement result and its associated uncertainty
The complete expression of the result!
Why do we need such small uncertainties?
