Latest Guides
Expert articles on US customary unit conversion
Gallons to Liters: US vs UK Confusion
A US gallon is 3.785 L; a UK (imperial) gallon is 4.546 L. Using the wrong one is a 20% error. Exact factors and a calculator.
Teaspoons & Tablespoons: Scaling Errors in Recipes
3 teaspoons = 1 tablespoon exactly. Swapping them, or mishandling fractions when scaling, ruins seasoning. Exact ratios and a per-ingredient converter.
TB vs GB Storage Confusion: Why Your Drive Looks Smaller
A "500 GB" drive shows ~465 GB because OSes use binary GiB. Decimal GB = 10⁹ bytes; binary GiB = 2³⁰. Exact factors and the calculator.
PSI, Bar, kPa: Mix-ups That Misread Pressure
1 bar ≈ 14.5038 psi; 1 atm = 14.6959 psi = 101.325 kPa. Confusing gauge with absolute pressure, or the units themselves, causes tire and engineering errors. Exact factors.
