In quantum mechanics, the
t P ≡ ℏ G c 5 displaystyle t_ mathrm P equiv sqrt frac hbar G c^ 5 where: ħ = h⁄2 π is the reduced
Solving the above will show the approximate equivalent value of this unit with respect to the second: 1 t P ≈ 5.391 16 ( 13 ) × 10 − 44
s displaystyle 1 t_ mathrm P approx 5.391,16(13)times 10^ -44 mathrm s The two digits between parentheses denote the standard error of the estimated value. Contents 1 Physical significance 2 See also 3 References 4 External links Physical significance[edit]
