About metric to imperial conversion

A metric to imperial converter helps translate measurements used in most of the world into units commonly encountered in the United States and, in some contexts, the United Kingdom. The supported pairs cover everyday distance, body or product mass, liquid capacity, and weather temperature. They are especially useful for travel, international shopping, technical drawings, imported product dimensions, recipes, and conversations between teams that work in different measurement systems. Meters convert to feet using the exact definition that one foot equals 0.3048 meter. Divide a meter value by 0.3048 to obtain feet. Kilometers convert to international miles using one mile equal to exactly 1.609344 kilometers. These exact relationships originate from the modern international definitions of the inch and yard, so they are appropriate for ordinary engineering and commercial calculations. A displayed decimal can still need rounding to match the precision of the source measurement. Kilograms convert to avoirdupois pounds using the exact factor 0.45359237 kilogram per pound. This is the pound used for most body weight, shipping, and retail goods in the United States. It is not a troy pound used for precious metals, and kilograms measure mass rather than force. Liters convert here to US liquid gallons using exactly 3.785411784 liters per gallon. A UK imperial gallon is approximately 4.54609 liters, so the word imperial is sometimes ambiguous in volume discussions. The calculator explicitly labels its result as US gallons to prevent that common mistake. Celsius and Fahrenheit require more than a multiplication factor because their zero points differ. Multiply Celsius by 9 divided by 5 and then add 32. Thus 0 degrees Celsius is 32 degrees Fahrenheit, while 100 degrees Celsius is 212 degrees Fahrenheit at standard pressure. A temperature difference is handled differently from an absolute reading because no 32-degree offset is added to a difference. The calculator retains useful decimal precision and removes unnecessary trailing zeros. Treat the answer as an accurate mathematical conversion, not as evidence that the original value was measured with equal precision. If a dimension is given only to the nearest centimeter, reporting many thousandths of a foot does not increase its real accuracy. Round according to the task, tolerance, recipe, or reporting standard you are following, and confirm whether a source means US customary or British imperial volume whenever gallons are involved.

Metric to imperial converter FAQ

How many feet are in one meter?

One meter equals approximately 3.280839895 feet. The conversion comes from the exact definition of one foot as 0.3048 meter.

How many miles are in one kilometer?

One kilometer equals approximately 0.6213711922 international mile. Multiply kilometers by that value or divide by 1.609344.

Does this tool use US or UK gallons?

This converter uses US liquid gallons, with one gallon equal to 3.785411784 liters. UK imperial gallons are larger and require a different conversion.

Why does Celsius need an offset?

Celsius and Fahrenheit place zero at different temperatures as well as using different degree sizes. The conversion therefore multiplies by 9 divided by 5 and adds 32.

Should converted values always show many decimals?

No. Keep enough decimals for the original measurement and intended use, because conversion cannot add measurement precision that was not present initially.
