- 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.
- Kilograms to PoundsBody weight, luggage, and gym plates: kg on the passport, pounds on the US scale. Multiply kg by 2.20462. A 23 kg bag is 50.7 lb — over many airline “50 lb” stickers if you packed to the kg limit.
- Long Tons to PoundsA British long ton is 2,240 lb (20 hundredweight). Ships and old coal invoices use it. A US short ton is 2,000 lb. If a UK document says “ton” it might be this one — 240 lb of difference per ton.
- Pixels to Emem is relative to the parent’s font-size, not the html root. Nested 1.2 em compounds. Padding in em grows with the text; that is either elegant or a layout bug.
- Pounds to KilogramsUS body weight and barbell math into the kg plates the rest of the gym already uses. Divide pounds by 2.20462. 150 lb is 68.0 kg, not “70 kg unless you are rounding for a form.”
- 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.

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.
