Simple syrup is a bartending and baking staple made by dissolving sugar in water — standard syrup uses equal parts sugar and water by volume (1:1), while "rich" simple syrup uses a 2:1 ratio for a more concentrated, longer-lasting syrup. This calculator finds the sugar amount needed for either ratio, in both volume and weight.
Measuring sugar by weight is more precise than by volume, since granulated sugar can pack differently depending on how it's measured.
How it works
Enter your water volume and choose standard (1:1) or rich (2:1) ratio. The calculator returns the sugar volume and weight needed, ready to dissolve together over gentle heat.
- Enter water (ml).
- Enter ratio.

Examples
Standard simple syrup for cocktails
For 240ml of water at a 1:1 ratio, the calculator returns 240ml (204g) of sugar to dissolve together.
Rich simple syrup for longer storage
For 240ml of water at a 2:1 ratio, the calculator returns 480ml (408g) of sugar for a more concentrated, longer-lasting syrup.
Who should use it
- Making simple syrup for cocktails and mocktails.
- Making syrup for sweetening iced coffee or tea.
Industry applications
- Bartending and mixology
- Coffee shops and beverage service
Advantages
- Gives both volume and weight measurements for precision.
- Covers both standard and rich syrup ratios.
- No account, subscription or watermark.
Limitations
- Does not account for flavored syrup variations (herbs, spices) — this is for plain simple syrup.
Common mistakes to avoid
- Not fully dissolving the sugar, leaving grainy syrup.
- Using the wrong ratio for the intended shelf life — rich syrup keeps longer than standard.
Best practices
- Heat gently and stir until the sugar is completely dissolved before cooling.
- Store finished syrup in a sealed container in the refrigerator.
Tips
- Rich (2:1) syrup keeps noticeably longer in the fridge than standard (1:1) syrup.
- Label and date stored syrup, since it can eventually develop mold if kept too long.
