Calculation steps
Work through one step at a time or reveal the complete calculation. The steps use your current inputs.
How to calculate
Apply the food-label salt-equivalent convention and ordinary mass-unit factors.
Salt equivalent(g)=sodium(mg)×2.5/1000
Worked example
400 mg sodium corresponds to 1 g salt equivalent. Conversely, 1 g salt equivalent corresponds to 400 mg sodium.
Assumptions and input details
Retain the same serving, package or per100gquantity basis. The2.5factor is a food-label convention using total sodium,including sodium from sources other than added sodium chloride. It is not an exact pure-compound molar-mass conversion or a measurement of added salt. No dietary allowance, medical advice, low-salt claim or jurisdiction-specific compliance assessment is supplied.
