Feet of Water Column (4 °C) To Standard Atmospheres Converter
Reverse Conversion
How This Converter Works
Convert between Feet of Water Column (4 °C) (ftH₂O (4 °C)) and Standard Atmospheres (atm). Select either direction to convert directly.
Formula or rule
Standard Atmospheres = Feet of Water Column (4 °C) * 0.0294997968911917; Feet of Water Column (4 °C) = Standard Atmospheres / 0.0294997968911917
Example
- Input
- 1 ftH₂O (4 °C)
- Calculation
- 1 * 0.0294997968911917 = 0.0294997968911917
- Result
- 0.0294997968911917 atm
Notes
Pressure scales are expressed in pascals. The bar is 100,000 Pa, the standard atmosphere is 101,325 Pa, the Torr is 1/760 of a standard atmosphere, and pounds-force per square inch uses the international pound-force and inch. Water-column values use the stated 4 °C or conventional definition.
