Formula
Megapascal = cm of Water × 9.8067e-5
Worked Example
Example: 5 cm of Water = 5 × 9.8067e-5 = 4.9033e-4 Megapascal
To convert cm of Water to Megapascal, multiply the cm of Water value by 9.8067e-5. This factor is derived from the ratio between the two units.
Centimeters of water is a unit of pressure defined as the pressure exerted by a column of water one centimeter high. It is primarily used in medicine for measuring airway pressure in ventilators and central venous pressure.
History
Centimeters of water became a standard unit in respiratory medicine because it represents pressures at a scale relevant to the human respiratory system. Normal airway pressures during mechanical ventilation typically range from 5-30 cmH₂O.
A megapascal is a unit of pressure equal to 1,000,000 pascals or 1,000 kilopascals. It is commonly used in engineering for measuring material strength, such as the tensile strength of steel and the compressive strength of concrete.
History
The megapascal is widely used in materials science and structural engineering. For example, typical concrete has a compressive strength of 20-40 MPa, while structural steel has a yield strength of approximately 250 MPa.

A responsive precision tool that fits in your pocket or dominates your desktop.
Each category converts first through a base unit, then into the destination unit. That keeps the math consistent across metric and imperial systems and makes it easier to explain how results are generated.
Use these tools for planning, study, and everyday reference. For regulated, medical, engineering, or procurement work, confirm requirements against the official standard or specification you are working from.
