Normally with a calculator you can just multiply the amount in kg by 2.2 to get lbs. Here's an easy way I just discovered on how to convert kg to lbs.
Multiple the number in kg by 2.
eg. 85 * 2 = 170
Divide that number by 10
eg. 170 / 10 = 17
Add the first and second number together:
eg. 170 + 17 = 187
That's it! (and that's also my current body weight: 187 pounds)
