- 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.
- 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.
- SI Gram Prefix ConverterMass prefixes attach to the gram, not the kilogram. Kilogram is already kilo + gram. Scale yottagram down to yoctogram, or milligram to microgram, without mixing in pounds. Jewelry carats and troy ounces are separate legal pages.
- Troy Ounces to GramsA troy ounce is exactly 31.1034768 g. Bullion, coins, and lab reagents in precious metals use troy, not avoirdupois. A “1 oz gold coin” is 31.103 g, not the 28.35 g kitchen ounce. 12 troy ounces make a troy pound; that pound is not the grocery pound.
- Atomic Mass Units to GramsDaltons (u) are how chemists weigh atoms. Carbon-12 is defined as 12 u. The gram is 6.022 × 10²³ of those, which is why a mole of carbon is 12 g. This page is for lab sheets, not grocery bags.
- 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.

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.
