Are Grams Equal to ML? ML to Grams for Water
Grams are equal to milliliters only when the density of the substance is exactly 1.0 g/mL(or 1 kg/L = 1000 kg/m³). This is the case for pure water at 4°C (39.2°F):
1 gram = 1 ml (water at 4°C / 39.2°F)
Even at room temperature (20-25°C or 68-77°F), we can still approximate that 1 gram equals 1 milliliter for water, as the density changes only slightly to about 0.998 g/mL. However, for other substances, the conversion depends entirely on their density.
Why Water's Density Matters
Water has unusual properties that make it essential for life. For example, ice is less dense than liquid water, which is why ice floats. This property helps protect aquatic life in winter, as the heaviest water (at about 4°C) sinks to the bottom, creating a stable environment even when the surface freezes. This is theorized to have been important when life was first developing.
How to Convert ML to Grams
Milliliters are a unit of volume, while grams are a unit of weight. Converting between them is not a simple multiplication or division by a constant. Instead, you need to know the substance's density.
Conversion Formulas
Volume [ml] = Weight [g] ÷ Density [g/ml]
or
Weight [g] = Volume [ml] × Density [g/ml]
Steps to Convert ML to Grams
- Find the density of the ingredient you want to convert. Our calculator includes 20+ common ingredients with pre-set densities.
- Select the ingredient from the dropdown, or choose "Custom ingredient" to enter your own density.
- Enter the volume in milliliters, and the calculator will automatically convert to grams.
- Or enter the weight in grams, and the calculator will convert to milliliters.
Common Ingredient Densities
| Ingredient | Density (g/mL) | Example |
|---|---|---|
| Water | 1.000 | 100 ml = 100 g |
| Milk | 1.030 | 100 ml = 103 g |
| Flour | 0.529 | 100 ml = 52.9 g |
| Sugar | 0.850 | 100 ml = 85 g |
| Salt | 1.200 | 100 ml = 120 g |
| Honey | 1.420 | 100 ml = 142 g |
| Butter | 0.911 | 100 ml = 91.1 g |
| Oil | 0.920 | 100 ml = 92 g |
| Oats | 0.400 | 100 ml = 40 g |
| Cacao | 0.600 | 100 ml = 60 g |
| Ice cream (premium) | 0.560 | 100 ml = 56 g |
| Ice cream (economy) | 0.500 | 100 ml = 50 g |
Note: Densities are approximations and may vary based on temperature, brand, and processing methods. For precise measurements, use weight (grams) rather than volume (milliliters).
Conversions from ML to Grams in Chemistry and Medicine
ML to grams conversions are essential in various scientific and medical applications:
- • Calculating medication dosages per kg of body weight
- • Converting liquid medicine concentrations (mg/mL)
- • Preparing solutions and suspensions
- • Measuring active ingredients in formulations
Example: If a medication is 50 mg/mL, then 10 mL = 500 mg = 0.5 grams
- • Preparing solutions with specific concentrations
- • Converting between volume and mass for reactions
- • Calculating molarity and molality
- • Measuring reagents for experiments
Example: For ethanol (density 0.789 g/mL), 100 mL = 78.9 grams
Tip: For chemistry and medicine applications, always use the specific density of your compound at the working temperature. Many compounds have density values listed in reference materials or safety data sheets (SDS). Use the "Custom ingredient" option in our calculator to enter these precise density values.
Conversion Examples
Given: 250 ml of water
Density: 1.0 g/mL
Calculation: 250 × 1.0 = 250 grams
Result: 250 ml = 250 g
Given: 200 ml of flour
Density: 0.529 g/mL
Calculation: 200 × 0.529 = 105.8 grams
Result: 200 ml = 105.8 g
Given: 150 grams of honey
Density: 1.42 g/mL
Calculation: 150 ÷ 1.42 = 105.6 ml
Result: 150 g = 105.6 ml
Given: 500 ml of milk
Density: 1.03 g/mL
Calculation: 500 × 1.03 = 515 grams
Result: 500 ml = 515 g
