Everything you need to know about kitchen conversions
Why does 1 cup of flour weigh differently than 1 cup of sugar?
Volume measures physical space, whereas weight measures actual mass. Flour has air pockets and a lower bulk density (about 120–125g per US cup), whereas granulated sugar crystals pack tightly and weigh approximately 200g per US cup. Kitchen Converter uses tested ingredient densities for exact measurements.
How does the air fryer conversion formula work?
Air fryers circulate dry, intense heat much faster than conventional ovens due to high-speed convection in a small chamber. The established culinary formula reduces the conventional oven temperature by 20°C (approx. 25°F) and shortens the cooking duration by roughly 20%, checking doneness slightly early.
Does the Kitchen Converter app work offline?
Yes! Kitchen Converter is built completely offline-first. All ingredient density formulas, temperature calculations, and unit conversions are stored locally on your device, ensuring instant results without Wi-Fi or cellular service.
What is the difference between US Cups and Metric Cups?
A US customary cup equals 236.6 ml (and a US legal cup is 240 ml), whereas a metric cup (common in Australia, New Zealand, and parts of the Commonwealth) is exactly 250 ml. Kitchen Converter accounts for regional variations so international recipes succeed.
Does Kitchen Converter collect recipe or personal data?
No. Kitchen Converter follows a strict privacy-first standard. We do not track recipes, we do not require user accounts, and we do not sell user data.
