Why do different ingredients convert differently?

Cups measure volume. Pounds measure mass. Each ingredient has a unique density, so the same volume weighs a different amount. One cup of all-purpose flour weighs about 0.28 lb, while one cup of honey weighs about 0.75 lb — nearly three times as much.

Are these conversions exact?

They are close approximations based on standard density references. Actual weight depends on how you fill the cup (scooped vs. spooned and leveled) and the specific brand or variety. For professional baking, use a kitchen scale.

Why is flour weight so variable?

How you pack flour into a cup changes its density significantly. A scooped cup can weigh 20% more than a spooned-and-leveled cup. This converter uses the spooned-and-leveled standard (0.28 lb per cup) which is the most common baking reference.

How do I convert the other way — pounds to cups?

Divide the pound value by the density factor for your ingredient. For all-purpose flour: pounds ÷ 0.28 = cups. This converter shows the density factor for each ingredient so you can do the reverse manually.

Does this handle fractions of a cup?

Yes. Enter any decimal value — 0.5 for half a cup, 2.25 for two and a quarter cups, and so on. The result updates immediately.
