How to use this data
CoolProp HEOS Water at pinned version/commit generates density ρ and dynamic viscosity μ offline. ν[cSt]=μ[Pa·s]/ρ[kg/m³]×10^6. Runtime uses the reviewed JSON; no property-service request is made.
CHECK THE METHOD
Worked example
At 20°C and 101325 Pa, water density is approximately 998.207 kg/m³ and kinematic viscosity approximately 1.0034 cSt.

Common lookup questions
Can I use these values as a universal specification?
Use an exact supported point. Temperature/pressure/composition affect fluid properties; this liquid-water subset does not cover brine, glycol, steam or high-pressure service.
