Planck momentum

Planck momentum is the unit of momentum in the system of natural units known as Planck units. It has no commonly used symbol of its own, but can be denoted by m P c {displaystyle m_{ ext{P}}c} , where m P {displaystyle {m_{ ext{P}}}} is the Planck mass and c {displaystyle c} is the speed of light in a vacuum. Then Planck momentum is the unit of momentum in the system of natural units known as Planck units. It has no commonly used symbol of its own, but can be denoted by m P c {displaystyle m_{ ext{P}}c} , where m P {displaystyle {m_{ ext{P}}}} is the Planck mass and c {displaystyle c} is the speed of light in a vacuum.
