The calculation
Price per lb = price per kg × 0.45359237
Worked example
At $12/kg, one pound costs $12 × 0.45359237 = $5.44310844, or about $5.44/lb. A 2 lb quantity weighs 0.90718474 kg and costs about $10.89 at that rate.
Use avoirdupois pounds, the same currency and comparable net contents. Round display prices at the end; changing the unit does not change the product’s value.

A product costs twelve dollars per kilogram. What is the equivalent price per pound? A pound is smaller than a kilogram, so the number of dollars for one pound should be smaller. The product and its value stay the same; only the comparison amount changes.
One avoirdupois pound is exactly zero point four five three five nine two three seven kilograms. For an everyday estimate, that is about zero point four five four kilograms. Keep the full conversion factor in the calculation, then round the final price to the precision you need.
Multiply twelve dollars per kilogram by zero point four five three five nine two three seven kilograms per pound. Kilograms cancel, leaving dollars per pound. The result is about five dollars and forty-four cents per pound. This unit cancellation tells you which direction the factor belongs.
Visually, one pound is a little less than half of a kilogram. Its price should therefore be a little less than half of twelve dollars. Half would be six dollars, and five dollars forty-four cents fits that check. A result above twelve would signal that the conversion went the wrong way.
For a two-pound quantity, double the unrounded per-pound price. The total is about ten dollars and eighty-nine cents. The same quantity is zero point nine zero seven one eight four seven four kilograms. Multiplying that mass by twelve dollars per kilogram gives the same total.
Suppose another store lists the same product at five dollars fifty cents per pound. Compare that with the converted rate of about five dollars forty-four cents per pound. The twelve-dollar-per-kilogram offer is slightly cheaper by unit mass, provided currency, product, net contents, and extra charges are treated consistently.
A displayed five dollars forty-four cents per pound is rounded. If you multiply that rounded number across a large order, the total can differ from using the original rate. Preserve the full factor and unrounded unit price for intermediate arithmetic. Unit conversion does not determine taxes, fees, or checkout rounding.
To convert price per kilogram to price per pound, multiply by zero point four five three five nine two three seven. Check that the number becomes smaller, and keep the currency and mass unit attached. Twelve dollars per kilogram is approximately five dollars and forty-four cents per pound.
