Calculation method
How the drink sodium concentration calculator works
Sodium mg/L = sodium mg / drink mL x 1,000; mmol/L = mg/L / 22.98976928.
The result describes the entered drink's sodium concentration only.
Worked example
Drink Sodium Concentration example
500 mg sodium in 1,000 mL equals 500 mg/L or about 21.75 mmol/L.
Sodium mg/L = sodium mg / drink mL x 1,000; mmol/L = mg/L / 22.98976928.
