Find the sugar and salt for a homemade sports drink.

Volume

Carb concentration (g/L)

Sodium (mg/L)

Calculated Output

Sugar needed 60

Table salt needed 1.27

Formula: sugar = carbs × volume; salt = sodium × 2.54 ÷ 1000

Step-by-Step Breakdown

1. Values used:

2. Volume = 1

3. Carb concentration = 60 g/L

4. Sodium = 500 mg/L

6. Sugar needed = Volume x Carb concentration = 1 x 60 = 60

7. Table salt needed = 1.27

Did this calculator solve your problem today?

The math behind it

Sugar = carbs/L × volume. Table salt is about 39% sodium, so salt grams = sodium mg × 2.54 ÷ 1000.

1 L at 60 g/L carbs, 500 mg/L sodium → 60 g sugar, ~1.3 g salt.

Why add salt?

Sodium replaces what you lose in sweat and aids fluid absorption.
