Chemistry and physics require many calculations involving temperature. of Clinical Chemistry (IFCC) recommended the use of selected, or favored, SI units for the clinical laboratory: whenever possible, use mole and liter units to express concentra- tion, and express whole-unit multiples of three as powers of ten (eg, millimole = 10 –3 I kelvin: K thermodynamic temperature "The kelvin, symbol K, is the SI unit of thermodynamic temperature.It is defined by taking the fixed numerical value of the Boltzmann constant k to be 1.380 649 × 10 −23 when expressed in the unit J K −1, which is equal to kg m 2 s −2 K −1, where the kilogram, metre and second are defined in terms of h, c and ∆ν Cs." It is expressed as m.s-1. Unit of mass, kilogram (kg): Kilogram is the SI unit of mass and is defined by taking the fixed value of the Planck constant. It is expressed as kg.m 2.s-1. Unit of time, second (s): Second is the SI unit of time and is defined by taking the fixed value of Cesium frequency.

It allows the reduction of zeros of a very small number or a very larger number such as 0.000 000 001 meter and 7,500,000 Joules into 1 nanometer and 7.5 Megajoules respectively. There are seven basic units in the SI system: the meter (m), the kilogram (kg), the second (s), the kelvin (K), the ampere (A), the mole (mol), and the candela (cd). What is a measurement in chemistry?
