How does the unit converter calculate results?
Each category has a base unit: the metre for length, the kilogram for weight, the litre for volume and the square metre for area. A value is converted into the base unit and then out to the target using exact definitions, such as 1 inch = 2.54 cm, 1 mile = 1,609.344 m, 1 pound = 0.45359237 kg and 1 US gallon = 3.785411784 litres. That is how 72 kg shows as 158.7328287731 lb and a 1,200 sq ft flat as 111.483648 square metres. Results are rounded to at most 10 decimal places and printed with thousands separators.
Temperature scales have different zero points, so they cannot share a single factor. The tool goes through Celsius, using F = C × 9/5 + 32 and K = C + 273.15: 37 °C is 98.6 °F, and -40 is the same on both scales. Under the result, the example line 1 °C = 33.8 °F is a single conversion and does not scale. Two degrees Celsius is 35.6 °F, while doubling 33.8 would give 67.6.
Which units are easy to mix up?
Volume units are US measures. A US gallon is 3.785411784 litres, while the imperial gallon used in the UK is 4.54609 litres, about 1.2 US gallons, so a British figure of 10 gallons is 45.4609 litres. The cup is the US cup of 236.5882365 mL. Recipes written for the 250 mL metric cup belong in the Cooking Unit Converter.
Feet and inches cannot be entered together, and decimal feet are a trap: 5.8 ft is 176.784 cm, while 5 ft 8 in is 68 inches, or 172.72 cm. Convert the total in inches, or use the Height Converter, which has separate feet and inch fields. Square yards are missing from the area list; one square yard is exactly 9 square feet, so divide a square-foot result by 9. A stone is 14 pounds, and 11 st converts to 69.85322498 kg.
How do you read the result?
The page opens on kilograms to pounds. Changing the conversion type resets both units to the first two in its list, and the swap button reverses them. An empty or non-numeric entry converts as 0, and negative values work, which matters for temperatures. Very small results lose detail at 10 decimal places: 1 mm in miles shows as 0.0000006214, so pick a closer unit when you need more digits.
