Physics constant, also called universal constant, are basic quantities observed in nature and the universe.  These physical constants are part of our everyday life and can be written in different units.

A

B

C

• Coulomb's Constant  -  The electric force constant, or the electrostatic constant, it is a proportionality constant in electrostatics equations. 

• Coulmbo's Wave Constant  -

D

• Dielectric Constant  -  The measure of a substance to an electric field expressed as the ratio of its electric displacement to the applied field strength.

E

F

G

• Gas Constant  -  See Universal Gas Constant

H

I

• Ideal Gas Constant  -  See Universal Gas Constant

J

• Josephson Constant  -

K

L

M

• Molar Gas Constant  -  See Universal Gas Constant

N

O

P

Q

R

S

• Specific Gas Constant  -  Deals with the universal gas constant which is equal to 8.314 joules per Kelvin.

• Spring Constant  -  The ratio of opposing force to the displacement from the origional position or how much force is needed to change a springs distance.

T

• Thermal Conductivity Constant  -

U

• Universal Gas Constant  -  When using these values in the Ideal Gas Law (or when making any calculation) make sure the units match up.)

• Universal Gravitational Constant  -  The proportionality constant used in Newton's Law of Universal Gravitation.  This constant is very difficult to measure with any high accuracy.
