Methodology
Water density and calculation basis
Evidence status: publishable.
Approximate density of air-free water at 25 °C, rounded to the nearest kg/m³.
temperature: 25 °C
composition: Air-free water
Source basis: NIST, NISTIR 7383 (2019), Selected Procedures for Volumetric Calibrations. GLP 10, Table 2, printed p.6 / PDF p.15, 25 °C air-free row. https://nvlpubs.nist.gov/nistpubs/ir/2019/NIST.IR.7383-2019.pdf Applicability: adopted-context.
For this direction, mass is calculated as volume multiplied by density after normalizing the units to cubic meters and kilograms. The resulting page multiplier is 235.878472 g per cup (US).
Use a measured density for a specific batch, grade or supplier; the table value is a reference, not a product specification.
