How accurate are the conversions?

Conversions use standard SI-defined ratios (e.g., 1 inch = 0.0254 m exactly). Temperature conversions use the standard offset formulas (°F = °C × 9/5 + 32). Results are accurate to JavaScript's 64-bit float precision.

Can I convert temperature units?

Yes. Select the Temperature category and choose from Celsius, Fahrenheit, Kelvin, or Rankine. The converter handles the non-linear offset formulas automatically.

What units are supported?

Length: mm, cm, m, km, in, ft, yd, mi, nautical miles. Weight: mg, g, kg, t, oz, lb, stone. Temperature: °C, °F, K, °R. Volume: ml to gallons. Area: mm² to square miles. Speed: m/s, kph, mph, knots, fps. Other: Nm and ft·lbs torque.

Does this work without internet?

Yes. Once the page loads, all calculations run locally in your browser. You can save it as a bookmark and use it offline.

Why do some conversion results have many decimal places?

Most unit ratios are irrational numbers (e.g., 1 mile = 1609.344 m). The result shows the full precision. Round to your needed decimal places for practical use.

1 Kilogram (kg) = 1,000 Gram (g)

Kilograms to grams is a simple metric conversion — 1 kg = 1000 g — yet it appears constantly in cooking, chemistry, pharmacy, and postal services. Baking precision: professional pastry recipes specify butter, flour, and sugar in grams (e.g., 0.25 kg butter = 250 g); gram-scale recipes are reproducible to ±1 g accuracy. Laboratory and chemistry: reagent quantities are often specified in grams but purchased in kilogram lots. Postal and shipping: the difference between 0.999 kg and 1.001 kg determines whether a parcel crosses a price tier. Precious metals: gold is traded in troy ounces (31.103 g) but often quoted per kilogram for large transactions. Coffee: a standard commercial bag is 1 kg (1000 g); a single espresso shot uses 7–9 g of ground coffee.
