# Why is Planck mass much larger than the smallest mass that we actually know about? [duplicate]

The three fundamental constants $h$, $c$ and $G$ are manipulated and rearranged in different ways to get the Planck time, Planck mass etc. The Planck time is said to be the smallest time possible and Planck length the smallest length(If I'm not mistaken). But, why the Planck mass doesn't fit to this list?

• Note that a Planck charge is about 11.7 elementary charges, which is neither the smallest charge that exists nor the smallest charge measurable. It's not even an amount of charge that exists given that charges come in multiples of 1/3. – David H Nov 10 '13 at 12:48
• The fact that if you calculate the "planck velocity" you would get the speed of light proves that planck units is not necessarily the smallest. – klutt Nov 15 '18 at 7:40
