Calculators are not always on hand at the gym or on a loading dock. Fortunately, the number 2.20462 lends itself cleanly to mental approximation. The simplest technique requires two basic addition steps:

Multiply the number of kilograms by 2, then add 10% of that doubled figure.

For 100 kilograms:

1. Step 1 (Double it): 100 × 2 = 200
2. Step 2 (Find 10% of the result): 10% of 200 = 20
3. Step 3 (Sum the two numbers): 200 + 20 = 220 lbs

This quick formula yields 220 lbs. Compared to the true value of 220.462 lbs, the mental shortcut produces an error margin under 0.21%. That small gap translates to less than a 7-ounce difference on a 220-pound object.
