Methodology

Seawater density and calculation basis

Evidence status: needs-review.

Seawater density depends on salinity, temperature and pressure.

method: Density calculated from temperature, salinity and in-situ pressure

Source basis: NOAA NCEI, World Ocean Atlas 2013 v2: density calculation. Density values calculation. https://www.nodc.noaa.gov/OC5/woa13/woa-info.html Applicability: context-only.

Select and document the adopted seawater conditions.

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 0.534627 lb per cup (US).

Use a measured density for a specific batch, grade or supplier; the table value is a reference, not a product specification.
