Water - Specific Gravity vs. Temperature

This tool provides specific gravity (relative density) data for water across a range of temperatures in both SI and Imperial units. Specific gravity is the ratio of the density of water to the density of a reference substance (typically water at 4°C or 20°C). The data includes density and specific gravity at multiple reference temperatures for temperatures ranging from 0°C to 374°C (32°F to 700°F).
