Can you convert cups to grams?
Cups measure volume and grams measure weight, so the link between them depends on the ingredient. The converter keeps volume and weight in separate sections and never converts between them. Water is the simple case, because 1 ml of water weighs about 1 g: a US cup of water (236.59 ml) weighs close to 237 g. Flour, sugar and butter each pack differently, and a cup of flour weighs far less than a cup of water, so a recipe that gives grams is the safer guide for baking.
Ounces carry the same trap. US fluid ounces in the Volume section measure space, 29.574 ml each, while ounces in the Weight section measure mass, 28.3495 g each. "8 oz chocolate" is a weight: 226.796 g, or half a pound. A line such as "8 fl oz milk" is a volume, exactly one US cup.
Which cup, spoon and pint sizes does the converter use?
All the spoons, along with the fluid ounce, pint, quart and gallon, are US measures: a teaspoon is 4.929 ml, a tablespoon 14.787 ml and a pint 473.18 ml. Fractions cannot be typed, so for 3/4 cup enter 0.75 with Cup (US) selected. You then see 177.442 ml, 12 tablespoons, 36 teaspoons, 6 US fluid ounces and 0.71 metric cups, rounded to three decimals with trailing zeros removed.
Two common measures are missing from the list. A British imperial pint is 568 ml; enter 568 with Millilitre (ml) selected and you get 1.2 US pints or 2.401 US cups. An Australian tablespoon is 20 ml, which comes to 1.353 US tablespoons or 4.058 teaspoons. Because the unit sizes are themselves rounded, some answers carry a small tail: 2 US cups shows 95.999 teaspoons, which is 96 for any kitchen purpose.
How do I convert oven temperatures between °C and °F?
The oven section applies the standard formulas. Multiply °C by 9/5 and add 32 to get °F, or subtract 32 from °F and multiply by 5/9 to get °C; results show one decimal place. A US recipe baked at 350 °F becomes 176.7 °C, and 180 °C is 356 °F, so on a dial marked in tens of degrees Celsius, 180 is the closest setting.
UK recipes often print a second, lower figure for fan ovens, as in 180 °C (160 °C fan), so convert the figure that matches your oven. Negative numbers work as well: a freezer at -18 °C reads -0.4 °F. For kelvin, stone and other units outside the kitchen, use the Unit Converter.
