Conversion between millimeters of water and millibar
You can easily convert between millibar [mbar] and millimeters of water [mmH₂O, mmWS] using the formulas provided below. For accurate results, it is important to follow the correct order of mathematical operations.
- Millimeters of water [mmH₂O, mmWS] = millibar [mbar] ÷ 9.80665 * 100
- Millibar [mbar] = millimeters of water [mmH₂O, mmWS] * 9.80665 ÷ 100
Conversion between millimeters of water and bar
The fastest and easiest way to convert between bar [bar] and millimeters of water [mmH₂O, mmWS] is to use the converter above. Manual conversions are also possible and can be done using the formulas provided below.
- Millimeters of water [mmH₂O, mmWS] = bar [bar] ÷ 9.80665 * 105
- Bar [bar] = millimeters of water [mmH₂O, mmWS] * 9.80665 ÷ 105
Conversion between millimeters of water and psi
The two formulas below provide an easy way to convert between psi [psi] and millimeters of water [mmH₂O, mmWS]. To ensure precise conversion results, it is important to follow the correct order of math operations.
- Millimeters of water [mmH₂O, mmWS] = psi [psi] * 4,535.9237 ÷ 6.4516
- Psi [psi] = millimeters of water [mmH₂O, mmWS] ÷ 4,535.9237 * 6.4516
Conversion between millimeters of water and pascals
You can easily convert between pascals [Pa] and millimeters of water [mmH₂O, mmWS] using the formulas provided below. For accurate results, it is important to follow the correct order of mathematical operations.
- Millimeters of water [mmH₂O, mmWS] = pascals [Pa] ÷ 9.80665
- Pascals [Pa] = millimeters of water [mmH₂O, mmWS] * 9.80665
Conversion between millimeters of water and metric tons per square meter
A quick and precise conversion between millimeters of water [mmH₂O, mmWS] and metric tons per square meter [t/m²] is straightforward and requires only multiplication or division by 1,000. The conversion from metric tons per square meter [t/m²] to millimeters of water [mmH₂O, mmWS] is done by multiplying the value in metric tons per square meter [t/m²] by 1,000. To reverse the conversion, divide the value in millimeters of water [mmH₂O, mmWS] by 1,000 to obtain metric tons per square meter [t/m²].
- Millimeters of water [mmH₂O, mmWS] = metric tons per square meter [t/m²] * 1,000
- Metric tons per square meter [t/m²] = millimeters of water [mmH₂O, mmWS] ÷ 1,000
