Orders of Magnitude and SI Units

Refers to the scale of measurement based on powers of ten.
Used to express very large or very small quantities simplistically, enhancing comprehension.

SI (Système International d'Unités) provides a standardized system of measurements.
Fundamental SI units interact with each other to represent different physical properties.

kilo (k): Represents a factor of 1,000 (10^3).
mega (M): Denotes a factor of 1,000,000 (10^6).
giga (G): Indicates a factor of 1,000,000,000 (10^9).
tera (T): Corresponds to a factor of 1,000,000,000,000 (10^12).
milli (m): Signifies a factor of one-thousandth (10^-3).
micro (u): Denotes a factor of one-millionth (10^-6).
nano (n): Represents a factor of one-billionth (10^-9).
pico (p): Corresponds to a factor of one-trillionth (10^-12).

metre (m): Unit of length; the basis for measuring distance.
kilogram (kg): Unit of mass; fundamental measure for weight.
second (s): Unit of time; standard for measuring intervals.
ampere (A): Unit for electric current; represents flow of electric charge.
mole (mol): Unit for amounts of chemical substances; essential in chemistry.
kelvin (K): Unit of temperature; scale based on absolute temperature.
candela (cd): Unit of luminous intensity; measures light brightness.

The scale of magnitudes is essential for fields such as physics, chemistry, and engineering.
Understanding SI units is critical for scientific communication, ensuring clarity across different disciplines.
