Centimeter water, 4°C – cmAq
Definition: cmAq is an uncommon abbreviation for pressure measured in centimeters of water at a specific temperature of 4°C.
Key Points:
- Informal Unit: Not a standardized unit for pressure. Use Pascals (Pa), kilopascals (kPa), or atmospheres (atm) for clarity.
- Temperature Dependence: Water density varies with temperature. “cmAq” only applies at 4°C.
- Conversion: 1 cmAq (at 4°C) ≈ 98.07 Pa.
Use Cases:
Limited to specific contexts where water is the working fluid and temperature is controlled at 4°C (e.g., legacy equipment).
