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 1.922992 cup (US) per lb.
