【JavaScript】if文で肥満度(BMI)を測る

Last updated at Posted at 2019-10-14

BMIによって肥満度を測ります。
heightに身長(メートル)、weightに体重(キロ)を入れる。

var height = 1.7;  //身長(m)
var weight = 60;  //体重(kg)

var BMI = weight/height/height;
console.log("BMIは" + BMI + "です");

var Taiju = height*height*22;
console.log("適正体重は" + Taiju + "kgです");


if ( BMI < 18.5) {
    console.log("痩せ気味です");
}
else if ( BMI < 25) {
    console.log("普通です");
}
else if( BMI < 30 ){
    console.log("肥満気味です");
}
else{
    console.log("高度肥満です");
}
