How to Convert Pound to Stone

Mathematically, stone (st) = pound (lb) multiplied by the conversion factor shown below.

1 lb = 0.071429 st

1 st = 14 lb

1 lb x 0.071429 = 0.071429 st

The mass in stone (st) is the mass in pound (lb) multiplied by 0.071429.

mass(st) = mass(lb) x 0.071429

Or:

st = lb x 0.071429

Formula: value × 0.0714285714286

Example: 15 lb = 1.071429 st

Example #1

Convert 10 pound to stone:

10 lb x 0.071429 = 0.714286 st

Example #2

150 lb x 0.071429 = 10.714286 st

  1. Start with the mass in pounds (lb).
