Weight in stones: stone to pounds conversion
In the UK and Ireland, weight is often expressed in stones. One stone equals 14 pounds (6.35 kg). Here's a quick reference:
| Stones | Pounds (lbs) | Kilograms (kg) |
|---|---|---|
| 6 stone | 84 lbs | 38.1 kg |
| 7 stone | 98 lbs | 44.5 kg |
| 8 stone | 112 lbs | 50.8 kg |
| 9 stone | 126 lbs | 57.2 kg |
| 10 stone | 140 lbs | 63.5 kg |
| 11 stone | 154 lbs | 69.9 kg |
| 12 stone | 168 lbs | 76.2 kg |
| 14 stone | 196 lbs | 88.9 kg |
For example, 6 stone equals 84 lbs or 38.1 kg. To convert stones to pounds, multiply by 14. To convert stones to kg, multiply by 6.35. The stone is still commonly used for body weight in the UK, while the US uses pounds and most other countries use kilograms.
FAQs
How do you convert feet and inches to centimeters?
Convert the total height to inches (feet × 12 + inches), then multiply by 2.54. For example, 5'8" = 68 inches × 2.54 = 172.72 cm. To go from cm to feet: divide by 2.54 to get inches, then divide by 12 for feet and use the remainder for inches.
What is the average height for men and women?
In the United States, the average height is 5'9" (175.3 cm) for adult men and 5'4" (162.6 cm) for adult women. Globally, the tallest populations are in Northern Europe (Netherlands averages 6'0" for men), while shorter averages are found in parts of Southeast Asia and Central America.
How do you measure height accurately?
Stand barefoot on a flat surface against a wall. Keep heels, buttocks, shoulder blades, and the back of your head touching the wall. Look straight ahead (the Frankfurt plane — the bottom of the eye socket level with the ear canal). Have someone place a flat object on your head touching the wall, and mark the spot. Measure from floor to mark.
When do you stop growing taller?
Most people stop growing in height by age 16–18 (girls typically finish by 14–16, boys by 16–18). Growth plates (epiphyseal plates) in the long bones close once puberty is complete. Some people may gain a small amount of height into their early 20s, but it's usually less than an inch.
What factors affect height?
Genetics account for about 60–80% of height variation. Nutrition (especially protein, calcium, and vitamin D during childhood) is the next biggest factor. Other factors include hormonal health, sleep quality, physical activity, and chronic illness during growth years. Socioeconomic status indirectly affects height through nutrition access.
How accurate are height predictors for children?
The mid-parental height method (average of parents' heights ± adjustment) predicts adult height within about 2 inches (5 cm) for most children. More accurate methods like the Khamis-Roche model use current height, weight, and parental heights. Bone age X-rays provide the most precise prediction but require medical imaging.
What is the average height by age for children?
Average heights for US children: Age 5: 42–43 inches (107–109 cm). Age 8: 50–51 inches (127–130 cm). Age 10: 54–55 inches (137–140 cm). Age 12: 58–60 inches (147–152 cm). Age 14: 63–66 inches (160–168 cm). Age 16: 64–69 inches (163–175 cm). Girls tend to hit growth spurts earlier (ages 10–14) while boys peak later (ages 12–16).
Which countries have the tallest and shortest people?
Tallest: The Netherlands leads with men averaging 6'0" (183.8 cm) and women 5'7" (170.4 cm). Montenegro, Denmark, and Norway follow. Shortest: Timor-Leste (men 5'3" / 160 cm), Laos, and Guatemala have some of the shortest average heights. The global trend is toward increasing height due to improved nutrition.
Does height affect BMI calculation?
Yes — BMI uses height squared in its formula (weight ÷ height²), so height significantly affects the result. Taller people tend to have higher BMI values even at similar body fat percentages, which is one of BMI's known limitations. Use our BMI calculator for your specific height-weight combination.
What is the formula to convert cm to feet and inches?
Divide centimeters by 2.54 to get total inches. Then divide by 12 — the quotient is feet, the remainder is inches. For example: 175 cm ÷ 2.54 = 68.9 inches. 68.9 ÷ 12 = 5 feet with 8.9 inches remaining. So 175 cm ≈ 5'9".
