Sodium & Salt Intake
Convert grams of salt to sodium and check against the daily limit.
About Sodium & Salt Intake
Table salt is roughly 39 percent sodium by weight, so grams of salt convert to milligrams of sodium accordingly. Most sodium comes from salt, so translating teaspoons into sodium makes daily intake easier to monitor.
Formula
Sodium & Salt Intake
Sodium = salt x 393 mg/g (salt is ~39% sodium by weight)
- 393
- Milligrams of sodium in one gram of salt
