Planck Mass Formula

\(\large{ m_p = \sqrt{ \frac{ h\;c } { G } } }\)   

Where:

 Units English SI
\(\large{ m_p }\) = Planck mass \(\large{lbm}\) \(\large{kg}\)
\(\large{ G }\) = gravitational constant \(\large{\frac{lbf-ft^2}{lbm^2}}\)  \(\large{\frac{N - m^2}{kg^2}}\) 
\(\large{ h }\) = Planck constant (reduced) \(\large{\frac{lbf-ft}{sec}}\) \(\large{J-s}\)
 \(\large{ c }\) = speed of light in vacuum  \(\large{\frac{ft}{sec}}\)  \(\large{\frac{m}{s}}\)
