This converter allows you to convert pounds per square inch [lb/in²] to meters of water [mH₂O, mWS] or meters of water [mH₂O, mWS] to pounds per square inch [lb/in²]. Calculations are performed in both directions. The calculation result and the entered value are displayed with up to 20 decimal places for maximum accuracy.

1 pound per square inch [lb/in²] ≈ 0.7031 meters of water [mH₂O, mWS]1 meter of water [mH₂O, mWS] ≈ 1.4223 pounds per square inch [lb/in²]

Convert pounds per square inch to meters of water

There are two simple ways to convert pounds per square inch [lb/in²] to meters of water [mH₂O, mWS]. In the first calculation method, the value in pounds per square inch [lb/in²] is divided by the rounded conversion factor of 1.4223. The second method multiplies the value in pounds per square inch [lb/in²] by the rounded conversion factor of 0.7031.

  • Meters of water [mH₂O, mWS] ≈ pounds per square inch [lb/in²] ÷ 1.4223
  • Meters of water [mH₂O, mWS] ≈ pounds per square inch [lb/in²] * 0.7031

However, rounded conversion values are only suitable for rough conversions, as rounding errors can occur in the calculation result. The most accurate conversion of pounds per square inch [lb/in²] to meters of water [mH₂O, mWS] can be achieved using the following calculation method.

  • Meters of water [mH₂O, mWS] = pounds per square inch [lb/in²] * 453.59237 ÷ 645.16

Convert meters of water to pounds per square inch

Converting meters of water [mH₂O, mWS] to pounds per square inch [lb/in²] is easy and can be done in two ways. The first method involves multiplication, in which the value in meters of water [mH₂O, mWS] is multiplied by the rounded conversion factor of 1.4223. The second variant is a division. Here, the value in meters of water [mH₂O, mWS] is divided by the rounded conversion factor of 0.7031.

  • Pounds per square inch [lb/in²] ≈ meters of water [mH₂O, mWS] * 1.4223
  • Pounds per square inch [lb/in²] ≈ meters of water [mH₂O, mWS] ÷ 0.7031

However, rounded conversion values do not allow for exact calculations because rounding errors can occur in the calculation result. The most accurate conversion of meters of water [mH₂O, mWS] to pounds per square inch [lb/in²] can be achieved using the following calculation method.

  • Pounds per square inch [lb/in²] = meters of water [mH₂O, mWS] ÷ 453.59237 * 645.16
