Pounds and Ounces to Kilograms
Convert a mixed pounds-and-ounces weight to kilograms, or enter kilograms to split the result into whole pounds and remaining ounces.
Pounds and ounces
Changing either value updates kilograms. Ounces greater than 16 are normalized through the total weight.
Kilograms
Changing kilograms updates whole pounds plus the remaining ounces.
Convert pounds and ounces to kilograms
Enter whole or decimal pounds in the first field and any remaining ounces in the second. The calculator combines both values before applying the exact international avoirdupois relationship of one pound to 0.45359237 kilograms. This is useful when a source weight is written as a mixed value such as 10 lb 8 oz.
Convert kilograms back to pounds and ounces
Enter kilograms on the right to calculate the total pounds, then split the fractional part into ounces. The displayed ounces are rounded to two decimal places. A scale, shipping service, form, or medical system may require a different number of decimal places, so follow its instructions.
Mass and length are different dimensions
Kilograms, pounds, and ounces measure mass or everyday weight. Meters, centimeters, feet, and inches measure length. There is no general kilogram-to-meter conversion without additional physical information. Use the Unit Converter for compatible length, weight, temperature, and volume pairs.
Practical checks
- Do not type a decimal-pound fraction into the ounces field without converting that fraction to ounces.
- Confirm whether a form expects total decimal pounds, mixed pounds and ounces, or kilograms.
- For medication, clinical care, aviation, trade, or another regulated calculation, verify the result with an approved method.
