See the <a href=\"https:\/\/www.cdc.gov\/bmi\/adult-calculator\/bmi-categories.html\" target=\"_blank\" rel=\"noreferrer noopener\">CDC adult BMI categories<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How BMI is calculated<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Metric BMI is weight in kilograms divided by height in metres squared: <strong>BMI = kg \u00f7 m\u00b2<\/strong>. With imperial measurements, use <strong>BMI = 703 \u00d7 lb \u00f7 in\u00b2<\/strong>. For example, 70 kg at 1.80 m gives a BMI of 21.6. See the complete <a href=\"https:\/\/calculatorsworld.com\/health\/bmi-formula\/\">BMI formula and worked examples<\/a>, or use the <a href=\"https:\/\/calculatorsworld.com\/health\/bmi-chart-men-women-metric\/\">metric BMI chart<\/a> and <a href=\"https:\/\/calculatorsworld.com\/health\/bmi-chart-men-women-imperial\/\">imperial BMI chart<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What the result can and cannot tell you<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>BMI is a screening measure, not a diagnosis.<\/strong> It does not distinguish body fat from muscle or bone and does not show where body fat is distributed. A healthcare professional may consider BMI together with medical history, physical examination and other health measures.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Adult categories should not be used to interpret a child or teenager&#8217;s result.
