A stone is a measure of weight in common usage in the UK. One stone is equal to 14 pounds. Knowing this conversion rate, it is easy to convert pounds to stones by dividing weight in pounds by 14. You can also convert weight in kilograms to stones by multiplying the weight in kilograms by .15747.

Steps

Converting Pounds to Stones

  1. Find your weight in pounds. Pounds are the U.S. standard unit for measuring mass or weight.[1] Most standard scales in the U.S. will weigh you in pounds, including scales at your doctor’s office, and personal scales you can buy.
    • For example, you might weigh 165 pounds.
  2. Divide your weight in pounds by 14. One stone is equal to 14 pounds. So dividing pounds by 14 will give you your weight in stones. [2]
    • For example, <math>\frac{165}{14} = 11.79</math>. So, 165 pounds is about 12 stone. Specifically, it is 11 stone, 11 pounds, since 165 divided by 14 is 11, with a remainder of 11.
  3. Convert stones to pounds. To do this, you need to do the opposite of what you would do to convert pounds to stones. That means you need to multiply the number of stones by 14. If the weight is given in the number of stones and pounds, multiply the number of stones by 14, and add the pounds to the product. Otherwise, just multiply the whole number or decimal by 14.
    • For example, to convert 10 stone, 8 pounds, you would calculate:
      <math>10 \times 14 + 8</math>
      <math>= 140 + 8</math>
      <math>= 148</math>
      So, 10 stone, 8 pounds is equal to 148 pounds.

Converting Kilograms to Stones

  1. Find your weight in kilograms. Kilograms are a standard metric unit for measuring mass. People around the world use kilograms to measure weight.
    • For example, you might weigh 70 kilograms.
  2. Multiply your weight by <math>.15747</math>. One stone’s weight is 15.747 percent of 1 kilogram. So multiplying the number of kilograms by .15747 will give you your weight in stones. [3]
    • For example, <math>70 \times .15747 = 11.0229</math>. So, 70 kilograms is about 11 stone.
  3. Convert stones to kilograms. To do this, you need to do the opposite of what you would do to convert kilograms to stones. So, you would divide the number of stones by .15747.
    • For example, to convert 9 stone to kilograms, you would calculate <math>\frac{9}{.15747} = 57.15</math>. So 9 stone is about 57 kilograms.

Solving Sample Problems

  1. Convert Chet’s weight in pounds to weight in stones. Chet weighs 174 pounds.
    • Divide the weight in pounds by 14: <math>\frac{174}{14} = 12.43</math>. So Chet weighs about 12 stone. You can also calculate <math>174 \div 14 = 12, R 6</math>. So specifically, Chet weighs 12 stone, 6 pounds.
  2. Convert the weight of metric ton into stones. A metric ton is 1,000 kilograms.[4]
    • Multiply the number of kilograms by .15747: <math>1,000 \times .15747 = 157.47</math>. So a metric ton is about 157 stone.
  3. Find the number of pounds that is equivalent to 8 stone.
    • There are 14 pounds in a stone, so multiply the number of stones by 14:<math>8 \times 14 = 112</math>. So, 8 stone equals 112 pounds.
