Planck's constant is h~~6.63*10^-34 \ "J"*"s".

Explanation:

Planck's constant, in science, is denoted by h, and is given the value of

h~~6.63*10^-34 \ "J"*"s"

Note that 1 \ "J"=1 \ "N"*"m"

=1 \ "kg"*"m/s"^2*"m"

=1 \ "kg"*"m"^2"/s"^2

And so, we can rewrite h as

h~~6.63*10^-34 \ "kg"*"m"^2"/s"^2*"s"

=6.63*10^-34 \ "kg"*"m"^2*"s"^-1

This is one of the smallest constants in physics, and gives the relationship between a photon's energy and its frequency.
