This converter allows you to convert meters of water [mH₂O, mWS] to millimeters of mercury [mmHg, Torr] or millimeters of mercury [mmHg, Torr] to meters of water [mH₂O, mWS]. Calculations are performed in both directions. The calculation result and the entered value are displayed with up to 20 decimal places for maximum accuracy.
Convert meters of water to millimeters of mercury
There are two simple ways to convert meters of water [mH₂O, mWS] to millimeters of mercury [mmHg, Torr]. In the first calculation method, the value in meters of water [mH₂O, mWS] is divided by the rounded conversion factor of 0.0136. The second method multiplies the value in meters of water [mH₂O, mWS] by the rounded conversion factor of 73.5559.
- Millimeters of mercury [mmHg, Torr] ≈ meters of water [mH₂O, mWS] ÷ 0.0136
- Millimeters of mercury [mmHg, Torr] ≈ meters of water [mH₂O, mWS] * 73.5559
However, rounded conversion values are only suitable for rough conversions, as rounding errors can occur in the calculation result. The most accurate conversion of meters of water [mH₂O, mWS] to millimeters of mercury [mmHg, Torr] can be achieved using the following calculation method.
- Millimeters of mercury [mmHg, Torr] = meters of water [mH₂O, mWS] * 98,066.5 ÷ 101,325 * 76
Convert millimeters of mercury to meters of water
Converting millimeters of mercury [mmHg, Torr] to meters of water [mH₂O, mWS] is easy and can be done in two ways. The first method involves multiplication, in which the value in millimeters of mercury [mmHg, Torr] is multiplied by the rounded conversion factor of 0.0136. The second variant is a division. Here, the value in millimeters of mercury [mmHg, Torr] is divided by the rounded conversion factor of 73.5559.
- Meters of water [mH₂O, mWS] ≈ millimeters of mercury [mmHg, Torr] * 0.0136
- Meters of water [mH₂O, mWS] ≈ millimeters of mercury [mmHg, Torr] ÷ 73.5559
However, rounded conversion values do not allow for exact calculations because rounding errors can occur in the calculation result. The most accurate conversion of millimeters of mercury [mmHg, Torr] to meters of water [mH₂O, mWS] can be achieved using the following calculation method.
- Meters of water [mH₂O, mWS] = millimeters of mercury [mmHg, Torr] ÷ 98,066.5 * 101,325 ÷ 76
