BMI Calculator

BMI Calculator is a person's weight in kilograms divided by the square of height in meters. BMI Calculator does not measure body fat directly, but research has shown that BMI is moderately correlated with more direct measures of body fat obtained from skinfold thickness measurements, bioelectrical impedance, densitometry (underwater weighing), dual energy x-ray absorptiometry (DXA) and other methods. Furthermore, BMI appears to be as strongly correlated with various metabolic and disease outcome as are these more direct measures of body fatness. In general, BMI is an inexpensive and easy-to-perform method of screening for weight category, for example underweight, normal or healthy weight, overweight, and obesity.

A high BMI can be an indicator of high body fatness. BMI can be used as a screening tool but is not diagnostic of the body fatness or health of an individual.

BMI计算器是一个人在用公斤身高米数的平方除以体重。 BMI计算器并不直接测量身体脂肪，但有研究表明，BMI适度与皮褶厚度测量，生物电阻抗，密度（水下称重），双能X线骨密度仪（DXA）获得身体脂肪更直接的措施相关，其它方法。此外，BMI出现是身体肥胖，这些更直接的措施，与各种代谢和疾病的预后密切相关。在一般情况下，体重指数是筛选重量类别，例如体重，正常或健康的体重，超重和肥胖的一种廉价的和易于执行方法。

高体重指数可高身体肥胖的指标。 BMI可用作筛选工具，但并不诊断个体的身体肥胖或健康的。
