Frequently Asked Questions
Verified answers and formulas for converting centimeters of water to megapascals.
There are 0.000098 megapascals (MPa) in 1 centimeter of water (cmH₂O). Conversely, 1 megapascal equals 10197.16213 centimeters of water.
To convert centimeters of water (cmH₂O) to megapascals (MPa), use the formula: MPa = cmH₂O × 0.0000980665. Multiply the centimeter of water value by 0.0000980665. For example, 10 cmH₂O equals 0.001 MPa.
To convert in the reverse direction from megapascals (MPa) to centimeters of water (cmH₂O), use the inverse formula: cmH₂O = MPa × 10197.16213. Multiply the megapascal value by 10197.16213 (1 MPa = 10197.16213 cmH₂O).
Both centimeter of water and megapascal measure pressure. Centimeter of Water (cmH₂O) is a unit in the Pressure measurement category. It is widely used in cpap & medical respiratory pressure. Relative to the pressure base unit, 1 cmH₂O equals 98.0665 Pascals (Pa). Megapascal (MPa) is a unit in the Pressure measurement category. It is widely used in megapascals (materials engineering). Relative to the pressure base unit, 1 MPa equals 1000000 Pascals (Pa).
1 bar equals approximately 14.5038 PSI. For car tires, 2.2 bar is roughly 32 PSI.
