kg

Lets write a C program to Convert weight from Kilograms to Pounds.

Note: 1 Kilogram is approximately equal to 2.20462 Pound.

kilogram to pound

Formula To Convert Weight From Kilograms to Pounds

pound = kilogram * 2.20462;

Logic To Convert Kilograms to Pounds

First we ask the user to enter weight / mass in kilograms. Then we multiply that value with 2.20462. The result itself is the pound equivalent of user entered weight in KG.

Source Code: C Program To Convert Kilograms to Pounds

#include<stdio.h>

int main()
{
    const float POUND = 2.20462;
    float kg;

    printf("Enter weight in Kilograms\n");
    scanf("%f", &kg);

    printf("Weight in Pounds is %f\n", (kg * POUND));

    return 0;
}

Output 1:
Enter weight in Kilograms
5
Weight in Pounds is 11.023099

Output 2:
Enter weight in Kilograms
14
Weight in Pounds is 30.864678

The Body Mass Index (BMI) is defined as ratio of the weight of a person(in kilograms) to the square of the height(in meters). Write a C program that receives weight and height, calculates the BMI, and reports the BMI category as per the following table:

BMI Category	BMI
Starvation	< 15
Anorexic	15.1 to 17.5
Underweight	17.6 to 18.5
Ideal	18.6 to 24.9
Overweight	25 to 25.9
Obese	30 to 30.9
Morbidly Obese	>= 40

Formula To Calculate Body Mass Index (BMI)

bmi = weight / (height x height);

Logic To Calculate BMI and BMI Category

We ask the user to enter weight in kelogram(kg) and height in meters(m). Then using above formula we calculate BMI(Body Mass Index). Next, by referring to the chart below we display the BMI category.

BMI Category

For BMI Category Ideal:
bmi >= 18.6 && bmi <= 24.9

Expected Output for the Input

User Input:
Enter height in meter
1.4
Enter weight in kg
60

Output:
Your Body Mass Index(BMI) is 30.612246
Your BMI category is: Obese

Source Code: C Program To Calculate BMI and BMI Category

#include < stdio.h >
int main()
{
    float height, weight, bmi;

    printf("Enter height in meter\n");
    scanf("%f", &height);

    printf("Enter weight in kg\n");
    scanf("%f", &weight);

    bmi = weight / (height * height);

    printf("Your Body Mass Index(BMI) is %f\n", bmi);

    if(bmi < 15)
    {
        printf("Your BMI category is: Starvation\n");
    }
    else if(bmi >= 15.1 && bmi <= 17.5)
    {
        printf("Your BMI category is: Anorexic\n");
    }
    else if(bmi >= 17.6 && bmi <= 18.5)
    {
        printf("Your BMI category is: Underweight\n");
    }
    else if(bmi >= 18.6 && bmi <= 24.9)
    {
        printf("Your BMI category is: Ideal\n");
    }
    else if(bmi >= 25 && bmi <= 25.9)
    {
        printf("Your BMI category is: Overweight\n");
    }
    else if(bmi >= 30 && bmi <= 30.9)
    {
        printf("Your BMI category is: Obese\n");
    }
    else if(bmi >= 40)
    {
        printf("Your BMI category is: Morbidly Obese\n");
    }
    else
    {
        printf("Wrong entry\n");
    }

    return 0;
}

Output 1:
Enter height in meter
0.8
Enter weight in kg
80
Your Body Mass Index(BMI) is 125.000000
Your BMI category is: Morbidly Obese

Output 2:
Enter height in meter
1.4
Enter weight in kg
50
Your Body Mass Index(BMI) is 25.510204
Your BMI category is: Overweight
