This converter allows you to convert millimeters of water [mmH₂O, mmWS] to megabar [Mbar] or megabar [Mbar] to millimeters of water [mmH₂O, mmWS]. 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 millimeter of water [mmH₂O, mmWS] ≈ 9.807 * 10-11 megabar [Mbar]1 megabar [Mbar] ≈ 1.02 * 1010 millimeters of water [mmH₂O, mmWS]

Convert millimeters of water to megabar

There are two simple ways to convert millimeters of water [mmH₂O, mmWS] to megabar [Mbar]. In the first calculation method, the value in millimeters of water [mmH₂O, mmWS] is divided by the rounded conversion factor of 1.02 * 1010. The second method multiplies the value in millimeters of water [mmH₂O, mmWS] by the rounded conversion factor of 9.807 * 10-11.

  • Megabar [Mbar] ≈ millimeters of water [mmH₂O, mmWS] ÷ (1.02 * 1010)
  • Megabar [Mbar] ≈ millimeters of water [mmH₂O, mmWS] * 9.807 * 10-11

However, rounded conversion values are only suitable for rough conversions, as rounding errors can occur in the calculation result. The most accurate conversion of millimeters of water [mmH₂O, mmWS] to megabar [Mbar] can be achieved using the following calculation method.

  • Megabar [Mbar] = millimeters of water [mmH₂O, mmWS] * 9.80665 ÷ 1011

Convert megabar to millimeters of water

Converting megabar [Mbar] to millimeters of water [mmH₂O, mmWS] is easy and can be done in two ways. The first method involves multiplication, in which the value in megabar [Mbar] is multiplied by the rounded conversion factor of 1.02 * 1010. The second variant is a division. Here, the value in megabar [Mbar] is divided by the rounded conversion factor of 9.807 * 10-11.

  • Millimeters of water [mmH₂O, mmWS] ≈ megabar [Mbar] * 1.02 * 1010
  • Millimeters of water [mmH₂O, mmWS] ≈ megabar [Mbar] ÷ (9.807 * 10-11)

However, rounded conversion values do not allow for exact calculations because rounding errors can occur in the calculation result. The most accurate conversion of megabar [Mbar] to millimeters of water [mmH₂O, mmWS] can be achieved using the following calculation method.

  • Millimeters of water [mmH₂O, mmWS] = megabar [Mbar] ÷ 9.80665 * 1011
