A cup of flour and a cup of honey weigh nothing like the same, so converting between volume and weight only works if you say what you are measuring. Choose your ingredient and this uses its actual density, alongside straightforward volume, weight and oven temperature conversion.
About 125 g for all-purpose flour in a US cup, though scooping straight from the bag can pack in 150 g or more. This is exactly why bakers weigh: the same "cup" can vary by 20%.
No. A US cup is 236.6 ml, a metric cup is 250 ml and an imperial cup is 284 ml. Australian tablespoons are 20 ml against 15 ml elsewhere. The converter lets you pick which system a recipe uses.
A fan (convection) oven runs roughly 20°C or 25°F cooler than a conventional oven for the same result. The oven section converts between Celsius, Fahrenheit, gas marks and fan settings.
