Although you measure your products in kilograms, you often get orders in both pounds and ounces. You have decided that rather than have to look up conversions all the time, you could use Python code to take inputs to make conversions between the different units of measurement. You will write three blocks of code. The first will convert kilograms to pounds and ounces. The second will convert pounds to kilograms and ounces. The third will convert ounces to kilograms and pounds. The conversions are as follows: 1 kilogram = 35.274 ounces 1 kilogram = 2.20462 pounds 1 pound = 0.453592 kilograms 1 pound = 16 ounces 1 ounce = 0.0283 kilograms 1 ounce = 0.0625 pounds For the purposes of this activity the template for a function has been provided.
