Unit Converters
- Milk Cups to MillilitersMilk and water weigh almost the same in a measuring cup. A US cup is 236.6 mL (8 fl oz). Nutrition labels round to 240 mL. Whole milk is slightly denser; it will not save a sauce that was 20 mL short.
- Metric Cups to MillilitersA metric cup is 250 mL. Australian and NZ recipes usually mean this. It is not the US customary cup (~236.588 mL) and not the US legal cup (240 mL) used on nutrition labels. If the cookbook is from Melbourne, start here.
- US Legal Cups to MillilitersUS nutrition labels define a cup as 240 mL. That is a legal rounding of the customary 236.588 mL cup. FDA serving math uses 240. Grandma’s Pyrex may still be closer to 236.6. Know which dictionary the label used.
- Brown Sugar Cups to GramsPacked light or dark brown sugar is about 220 g per US cup. “Packed” means you pressed it. A loose scoop can miss 30 g and flatten cookies. Light and dark weigh nearly the same; molasses is the flavor, not the scale.
- Cocoa Powder Cups to GramsUnsweetened cocoa powder is fluffy. A US cup is about 85 g sifted/spooned. Dutch-process vs natural does not change the gram target as much as how hard you tap the cup.
- Dry Rice Cups to CookedWhite long-grain usually triples: 1 dry cup → about 3 cooked. Brown rice is closer to 2–2½. Risotto soaks differently. This is a pot estimate, not a lab yield.

Unit Converters
A 5K is 5,000 meters, not 5 kilometers on the nose if your watch is sloppy. Divide meters by 1,000. Track races, building plans, and “how far was that hike” all live in this split.
Feet to Meters
Unit Converters
US height, ceiling height, and lumber still arrive in feet. Meter plans do not. One foot is exactly 0.3048 m — not “about a third.” Use this when a listing says 10 ft ceilings and the architect works in meters.
Inches to Centimeters
Unit Converters
Monitor diagonals, waist measurements, and photo prints still come in inches. Clothing charts in Europe come in cm. Multiply inches by 2.54. That factor is exact, not a kitchen guess.

Very usable on mobile. Would love a save/export option later, but the math feels solid.
