inH2O to Torr converter
1 inH2O = 1.86827 Torr
And 1 Torr = 0.535255 inH2O. Inches of water column to torr.
Formula
Torr = inH2O × 1.86827
A reading of 15 inH2O is 15 × 1.86827 = 28.024 Torr.

About these units
inH2O (inches of water column): Low duct and furnace pressures, at the conventional 4 °C water reference.
Torr (torr): Vacuum technology: 1/760 of a standard atmosphere.
Gauge pressure (psig, barg) is measured relative to the surrounding atmosphere; absolute pressure (psia, bara) is relative to vacuum. Converting units never changes that reference: absolute = gauge + about 14.696 psi (1.01325 bar) at sea level. Stress uses the same units: 1 MPa = 1 N/mm².
