Specific Weight Fluid Pressure in Measurement of Physical Parameters Formulas

No, the Specific Weight Fluid Pressure, measured in Specific Weight cannot be negative.

Specific Weight Fluid Pressure is usually measured using the Kilonewton per Cubic Meter[kN/m³] for Specific Weight. Newton per Cubic Meter[kN/m³], Newton per Cubic Centimeter[kN/m³], Newton per Cubic Millimeter[kN/m³] are the few other units in which Specific Weight Fluid Pressure can be measured.
