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.
The official kilogram weight lost 0.0001g, which is around the weight of a dust particle, in the last century, meaning the official weight is becoming less accurate. The researchers have now found they can produce a reliable and accurate definition of the kilogram that does not change by calculating it in mathematical terms.
