The newton is a measurement of force that includes kilograms in its definition and cannot be explicitly described in terms of kilograms. One newton is equal to 1 kg * m/s².
As a result of this relationship, the equation can be rearranged to represent kilograms in terms of newtons, meters and seconds, but a direct equivalency between newtons and kilograms cannot be derived. However, as m/s² is a measurement of acceleration, it can be stated that 1 kg is equal to 1 N (newton) divided by acceleration. Stated otherwise, 1 kg = 1 N * s²/m. In other words, 1 kg is equal to 1 N times seconds times seconds divided by meters.
