Use the below force conversion chart to convert into different units of force. Choose your beginning unit value on the left and then find the cell where it aligns with the final value you seek across the top of the chart. Multiply the value in that cell by your starting unit of force to calculate your desired unit of force. Example: Converting from “Ounce” to “Kilogram” would require multiplying your starting force value by 0.4536. 15 Ounces x 0.0283 = 0.4245 Kilograms.
