A national law enforcement agency is a LEA in a country which does not have divisions capable of making their own laws. A national LEA will have the combined responsibilities that federal LEAs and divisional LEAs would have in a federated country. National LEAs are usually divided into operations areas.
A kilogram is more than twice as heavy as a pound. A kilogram consists of 1,000 grams, while the mass of 1 pound is only 453.6 grams, or less than half a kilogram.
at your own risk :-) Basically 1 kilogram equals 2.2046 pounds (there's a longer decimal position but I shorten it to 2.2046) With that in mind, you know that one kilogram is heavier than one pound and therefore the 'per kilogram' price will always be HIGHER than the 'per pound' price.
