- Fluid Ounces to MillilitersUS fl oz × 29.57 = mL. An 8 oz cup of coffee is 237 mL. UK fl oz is 28.4 mL. Bottle labels that say 12 fl oz are 355 mL — the beer can you already know.
- Cups to MillilitersUS customary cup is 240 mL in nutrition labels and 236.6 mL in the true fluid-cup (8 fl oz). This page uses the 8 fl oz cup (236.6 mL). A “metric cup” in Australia is 250 mL. If the cake falls, check which cup the author owned.
- Fluid Ounces to Cups8 US fl oz make a cup. A 12 oz can is 1½ cups. UK fluid ounces are 28.4 mL, not 29.6 — close until you scale a catering recipe.
- Ounces to GramsUS recipes still say 8 oz of chocolate. European scales only know grams. Multiply ounces by 28.35. If the recipe meant a fluid cup, you are in the wrong aisle — that is volume.
- Pounds to OuncesSixteen avoirdupois ounces in a pound. Shipping labels and baby weight still mix them: 7 lb 8 oz is 120 oz total. Multiply pounds by 16. No troy, no fluid ounces.
- Butter Sticks to GramsA US stick is ½ cup, 8 tablespoons, 4 oz, 113 g. European blocks are often 250 g. If a UK recipe says “8 oz butter,” that is two US sticks, not a European brick.

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.
