How to Convert ksi to Inch of Mercury
- 1 ksi = 2036.020677 inHg
- 1 inHg = 0.0004911541475 ksi
- Example: convert 15 ksi to inHg: 15 ksi = 15 × 2036.020677 inHg = 30540.31016 inHg
Reference conditions. inHg: Conventional mercury column: ρ = 13 595.1 kg/m³ and gₙ = 9.80665 m/s² (≈ mercury at 0 °C / 32 °F).
Formula
inHg = ksi × 2036.020677318
Derivation from SI units:
- 1 ksi = 1000 psi = 1 kip/in² = 6.894757293168 MPa
- 1 inHg = 13 595.1 kg/m³ × 9.80665 m/s² × 0.0254 m = 3386.388640341 Pa
- 1 ksi = 6894757.293168 Pa ÷ 3386.388640341 Pa per inHg = 2036.020677318 inHg
Both units are defined exactly, so the factor is exact. ksi definition: ksi; Inch of Mercury definition: inch of mercury.
Worked examples
- A reading of 20 ksi converts to 40720.41355 inHg.
20 ksi × 2036.020677 = 40720.41355 inHg - A value of 65 ksi is 132341.344 inHg.
65 ksi × 2036.020677 = 132341.344 inHg
