Dimensional-analysis
A method in physics and chemistry for converting one unit of measurement into another, using the fact that the dimensions of the quantity must remain the same.
Kilograms
The base unit of mass in the International System of Units (SI), equivalent to one thousand grams, used globally for measuring weight.
Pounds
A unit of weight in the imperial system, equivalent to 0.453592 kilograms.
