- 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.
- BMI Metric and ImperialBMI = kg / m² = 703 × lb / in². Same index, two unit systems. It does not know muscle, bone, or why a powerlifter and a couch get the same number. Categories are public-health bins, not a diagnosis.
- 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.
- 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.
- 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.
- Grams to OuncesCoffee bags, protein scoops, and postage: grams on the label, ounces in US recipes. Divide grams by 28.3495. This is the avoirdupois ounce (16 in a pound), not the troy ounce jewelers use.

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.
