Converting milliliters (ml) to grams (g) is a common requirement in cooking, chemistry, health, and industrial tasks. But unlike simple unit changes, this conversion depends on the density of the material being measured. That’s because milliliters measure volume, while grams measure mass.
For custom, enter the density in g/ml.
.
📏 What Is the Milliliters to Grams Calculator?
The Milliliters to Grams Calculator is an interactive tool that converts a liquid’s volume (ml) into weight (g) using the density of the material. It’s useful for:
- Cooking and baking
- Nutrition and dieting
- Pharmaceutical measurements
- Scientific experiments
- Industrial mixing or production
🧮 How Does It Work?
Unlike fixed unit conversions, this calculation requires density. The formula is:
Grams = Milliliters × Density (g/ml)
Default Conversion for Water:
- Since water’s density = 1 g/ml,
→ 1 ml of water = 1 gram
For all other substances, density varies and must be applied.
🛠️ How to Use the Milliliters to Grams Calculator
Step 1: Enter Volume in Milliliters
Example: 200 ml
Step 2: Select or Enter the Substance
Choose from a list (e.g., milk, olive oil) or enter a custom density.
Step 3: Click “Calculate”
The tool will output the equivalent grams using the formula.
📐 Formula Breakdown
Grams (g) = Milliliters (ml) × Density (g/ml)
Examples:
- 100 ml of water → 100 × 1.0 = 100 g
- 150 ml of honey (1.42 g/ml) → 150 × 1.42 = 213 g
- 75 ml of olive oil (0.91 g/ml) → 75 × 0.91 = 68.25 g
📊 Densities of Common Substances
| Substance | Density (g/ml) |
|---|---|
| Water | 1.00 |
| Milk | 1.03 |
| Olive Oil | 0.91 |
| Honey | 1.42 |
| Sugar (gran.) | 0.85 |
| Flour (sifted) | 0.59 |
| Butter (melted) | 0.911 |
| Alcohol | 0.789 |
You can use these preset densities or input your own in the calculator.
🔢 Example Conversions
🧁 Example 1: Milk in Baking
300 ml milk × 1.03 = 309 g
🧪 Example 2: Alcohol in Chemistry
100 ml × 0.789 = 78.9 g
🥞 Example 3: Honey for Breakfast
50 ml × 1.42 = 71 g
⚖️ Quick Reference Table
| Milliliters (ml) | Water (g) | Milk (g) | Honey (g) | Olive Oil (g) |
|---|---|---|---|---|
| 50 | 50 | 51.5 | 71 | 45.5 |
| 100 | 100 | 103 | 142 | 91 |
| 250 | 250 | 257.5 | 355 | 227.5 |
| 500 | 500 | 515 | 710 | 455 |
| 1000 | 1000 | 1030 | 1420 | 910 |
✅ Why Use This Calculator?
- 🔹 Precision – Accurate results for any ingredient or chemical
- 🔹 Time-saving – No need to calculate manually
- 🔹 Versatile – Works with hundreds of substances
- 🔹 Essential for science, cooking, and diet planning
🧠 When Do You Need to Convert ML to G?
- Cooking and baking – For recipes that specify one or the other
- Nutrition tracking – When labeling uses grams but volume is easier to measure
- Science labs – Where exact substance mass is required
- Manufacturing – For quality-controlled ingredient mixing
🔄 How to Convert Back (Grams to ML)
You can also reverse the formula:
Milliliters = Grams ÷ Density
Example:
200 g of olive oil → 200 ÷ 0.91 ≈ 219.78 ml
❓ 20 Frequently Asked Questions (FAQs)
1. Is 1 ml always equal to 1 gram?
Only for water or substances with a density of 1 g/ml.
2. Why does honey weigh more than water?
It’s denser—1.42 g/ml vs. 1 g/ml for water.
3. What’s the density of milk?
Approximately 1.03 g/ml.
4. How do I find the density of an unknown substance?
Check scientific charts, packaging labels, or measure it experimentally.
5. Can I convert ml to grams for dry goods like flour?
Yes—but you’ll need the volumetric density of the dry good.
6. Is this calculator good for chemical measurements?
Yes, as long as you input the correct density for the chemical.
7. Can temperature affect density?
Yes—especially for liquids. Density changes slightly with heat.
8. How do I convert 250 ml of olive oil to grams?
250 × 0.91 = 227.5 grams
9. Does the calculator round the result?
It can show decimals up to 2–3 places for accuracy.
10. Is this suitable for nutrition tracking apps?
Yes—great for food tracking and meal planning.
11. Why do recipes sometimes give both units?
To help people who measure by volume or by weight.
12. What’s the density of granulated sugar?
Approximately 0.85 g/ml.
13. Is butter heavier than water?
No—melted butter is slightly less dense than water (0.911 g/ml).
14. What is 1 liter of water in grams?
1000 grams (because 1000 ml × 1 = 1000 g).
15. Can I use this calculator offline?
Depends on the platform—many apps or web tools require internet.
16. Is this useful for baristas or bartenders?
Yes—especially for syrups, alcohols, and milk.
17. Can I convert alcohol with this tool?
Yes—use density of ~0.789 g/ml.
18. What is the difference between ml and grams?
ML measures volume; grams measure mass.
19. Do you have a grams to ml converter too?
Yes—just reverse the formula or request the dedicated tool.
20. Is the calculator free to use?
Yes—completely free and unlimited.
