1
Rewrite psi in the base unit
$1 psi = 6, 894.76 Pa$
2
Rewrite Torr in the base unit
$1 Torr = 133.322 Pa$
3
Forward conversion
$1 psi = \frac{6 , 894.76 Pa}{133.322 Pa} \times 1 Torr = \frac{6 , 894.76}{133.322} Torr = 51.7150957831 Torr$
4
Reverse conversion
$1 Torr = \frac{133.322 Pa}{6 , 894.76 Pa} \times 1 psi = \frac{133.322}{6 , 894.76} psi = 0.019336713678 psi$
