How much does one tablespoon of flour weigh compared to a tablespoon of sugar, olive oil, or honey? And how many grams are in 1 US Cup (240 ml) when baking pancakes, cookies, or cakes without a scale? The biggest flaw in generic unit converters is assuming 1 ml = 1 gram for everything: in reality, all-purpose flour has a bulk density of 0.53 g/ml (so a 240 ml cup weighs just 125–127 g!), granulated sugar is 0.85 g/ml (1 Cup = 200 g), and honey is 1.42 g/ml (1 Cup = 340 g).

Detailed Technical Guide: Top 10 Practical Cases & Factors
#1 All-Purpose, 00 & Bread Flour (Density 0.53 g/ml) 1 Cup = 127 g
Sifted wheat flour traps air pockets between particles: 1 level tablespoon weighs 8 g (12 g heaped), a 200 ml drinking glass holds 106 g, and 1 standard US Cup equals 125–127 g.
✅ Key Takeaways & Practical Advantages
- To measure 100 g of flour without a scale, fill a 200 ml glass to 95% or use 8 heaped tablespoons
⚠️ Common Mistakes to Avoid
- Never scoop and pack flour tightly into a cup, or it will weigh 155 g and dry out your cake
#2 Cornstarch & Potato Starch (Density 0.50 g/ml) 1 Tbsp = 7.5 g
Pure starches are lighter than wheat flour: 1 level tablespoon of cornstarch or potato starch weighs 7.5 g (10 g heaped) and 1 US Cup weighs 120 g.
✅ Key Takeaways & Practical Advantages
- Easy to dose by the spoonful when thickening custards and sauces
⚠️ Common Mistakes to Avoid
- Always fluff and level with a knife blade before measuring
#3 Granulated Sugar vs Powdered Sugar (0.85 vs 0.56 g/ml) 1 Cup = 200 g / 135 g
Granulated white sugar crystals have a 0.85 g/ml density: 1 level tablespoon weighs 13 g, 1 teaspoon is 4.2 g, a 200 ml glass holds 170 g, and 1 US Cup is 200 g. Powdered sugar is much lighter at 0.56 g/ml (1 Cup = 135 g).
✅ Key Takeaways & Practical Advantages
- Granulated sugar does not compact, making volume cups remarkably accurate
⚠️ Common Mistakes to Avoid
- Moist brown sugar is traditionally measured packed (1 packed Cup = 215 g)
#4 Butter: Sticks, Cups & Tablespoons (Density 0.91 g/ml) 1 Cup = 220 g
US recipes measure butter in sticks or cups: 1 stick of butter equals 1/2 US Cup (8 tablespoons) and weighs 113 grams. One full US Cup of butter weighs 220–226 g.
✅ Key Takeaways & Practical Advantages
- 1 tablespoon of butter equals a 14-gram pat
⚠️ Common Mistakes to Avoid
- European 250 g butter blocks usually have 25 g ruler markings printed on the wrapper
#5 Extra Virgin Olive Oil & Vegetable Oils (0.92 g/ml) 1 Tbsp = 14 g
All culinary oils are less dense than water: 100 ml of olive oil weighs 92 grams, not 100 g! One 15 ml tablespoon holds 13.8 g of oil (~122 kcal).
✅ Key Takeaways & Practical Advantages
- Makes dressing salads with a spoon accurate without a scale
⚠️ Common Mistakes to Avoid
- When a cake calls for 100 g of oil, pour up to the 109 ml mark on a liquid measuring jug
#6 Honey, Maple Syrup & Molasses (Density 1.42 g/ml) 1 Tbsp = 21 g
Honey is nearly 1.5 times heavier than water (1.42 g/ml): a single level tablespoon weighs 21 grams, and a 240 ml US Cup holds 340 grams of honey.
✅ Key Takeaways & Practical Advantages
- Pro tip: coat your measuring spoon with a drop of oil first so honey slides right off
⚠️ Common Mistakes to Avoid
- Crystallized honey must be gently warmed to measure accurately by volume
#7 Water, Milk, Broth, Wine & Liquid Cream (1.00 g/ml) 1 ml = 1 g
For water, milk, plant milks, broth, vinegar, and wine, specific gravity is virtually 1.00 g/ml (whole milk is 1.03 g/ml): grams and milliliters are 1:1 interchangeable.
✅ Key Takeaways & Practical Advantages
- A standard drinking glass filled 1 cm below the rim holds 200 ml = 200 g
- An espresso demitasse cup holds 60 ml = 60 g
⚠️ Common Mistakes to Avoid
- Sweetened condensed milk is much denser (1.28 g/ml: 1 Cup = 306 g)
#8 Uncooked Rice Grains vs Rolled Oats (0.85 vs 0.36 g/ml) 1 Glass = 170 g Rice
When cooking without a scale, a drinking glass measures rice with pinpoint accuracy: 1 level 200 ml glass of raw rice weighs 170 g (ideal for 2 people!), while 1 espresso cup holds 55 g. Rolled oats are much lighter (1 US Cup = 86 g).
✅ Key Takeaways & Practical Advantages
- 1 glass of rice + 2 glasses of water = foolproof absorption rice for 2 people
⚠️ Common Mistakes to Avoid
- Do not use glasses to measure dry pasta shapes due to large air gaps
#9 Cocoa Powder, Baking Powder & Salt (0.45 / 1.20 g/ml) Micro-Dosing
For small amounts under 5 grams where basic kitchen scales lose sensitivity, a level 5 ml teaspoon is actually more reliable: 1 level teaspoon of fine table salt is 6 g, baking soda is 5.5 g, and baking powder is 5 g.
✅ Key Takeaways & Practical Advantages
- More reliable than standard load-cell scales for 1–5 g quantities
⚠️ Common Mistakes to Avoid
- Coarse kosher or sea salt has air gaps and weighs less per spoon than fine table salt
#10 Oven Temperature Conversion: °F ↔ °C Conventional ↔ Convection Fan -20°C Fan Rule
US baking recipes list oven temperatures in Fahrenheit (°F) assuming a conventional static oven: 350°F equals 175–180°C. When baking with a convection fan enabled, always reduce temperature by 20°C (25°F).
✅ Key Takeaways & Practical Advantages
- Quick °F to °C formula: subtract 32, then divide by 1.8
⚠️ Common Mistakes to Avoid
- Use static heat (fan off) for delicate sponge cakes and soufflés so the top does not set too early
