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, volume is calculated as mass divided by density after normalizing the units to kilograms and cubic meters. The resulting page multiplier is 0.00423947 cup (US) per g.
Use a measured density for a specific batch, grade or supplier; the table value is a reference, not a product specification.
