- How many grams is 1 mL?
- For water, 1 gram. For anything else, 1 mL weighs its density in grams: 1 mL of milk is about 1.03 g, olive or vegetable oil about 0.92 g, honey about 1.42 g, granulated sugar about 0.85 g, and all-purpose flour about 0.53 g. That's why a converter that assumes water gets baking wrong — a millilitre of flour weighs roughly half a millilitre of water.
- How many grams is 250 mL?
- 250 g of water. The same 250 mL is 257.5 g of whole milk, 230 g of oil, 355 g of honey, 211.25 g of granulated sugar, and 132 g of spooned all-purpose flour. 250 mL is also a metric cup, so if a recipe from Australia, Canada, or the UK says "1 cup," these are the weights it's asking for.
- Why doesn't 1 mL always equal 1 gram?
- Millilitres measure how much space something takes up; grams measure how heavy it is. Water lines up because the metric system was built on it — the gram was first defined in 1795 as the mass of a cubic centimetre of water. Everything else is heavier or lighter than water for its size. Oil floats on water because it's lighter per mL; honey sinks because it's heavier. Even water isn't exactly 1 g/mL at room temperature (it's closer to 0.998), but that's two grams per litre — well below what a kitchen scale reads.
- How do I convert mL of flour to grams?
- Multiply by about 0.53 for all-purpose flour that's spooned into the measure and leveled: 250 mL is 132 g, 100 mL is 52.8 g. Scooping straight from the bag packs the flour and can add up to 20%, so the same 250 mL can weigh as much as 158 g. That swing is the reason bakers switch to scales. If the recipe was written in grams, weigh; if it was written in volume, the spooned figure is the safer guess.
- How do I find the density of something that isn't on the list?
- Check the nutrition label. Most list a serving in both volume and weight, like "1 tbsp (15 mL), 14 g." Divide the grams by the millilitres — 14 ÷ 15 = 0.93 g/mL — and type that into the density box. For chemicals and liquids, safety data sheets list density, often as g/cm³ (the same number as g/mL) or kg/m³ (divide by 1,000). If you weigh a known volume yourself, grams ÷ millilitres gives you the same number.
- Is a millilitre the same as a cc or a cubic centimetre?
- Yes. 1 mL = 1 cc = 1 cm³, exactly. Medicine syringes and engine sizes often say cc; recipes and drink labels say mL. The tool accepts all three, so 5 cc of water converts to 5 g.
- How many grams is a tablespoon or a cup?
- A US tablespoon is 14.79 mL and a US cup is 236.59 mL; metric versions are 15 mL and 250 mL. Multiply by the density: a US tablespoon of honey is about 21 g, a metric cup of sugar about 211 g. If you type "2 cups" or "1 tbsp" here, the tool tells you the millilitres to enter. For recipes written in cups or spoons, the cups to grams and tablespoon to grams converters skip that step.
- How accurate are the ingredient densities?
- Liquids are close — water, milk, oil, honey, and syrup don't settle or pack, so the numbers hold within a percent or two. Powders and grains are averages: flour, sugar, cocoa, and oats vary with brand, humidity, and how they were measured. Treat those as a good starting point for everyday cooking, and weigh the ingredient when a recipe is precise, like bread dough or macarons.
- Is what I type saved or sent anywhere?
- No. The conversion runs in your browser. Nothing is sent to a server or stored, and closing the tab clears it.
