In section 28, i cant figure where's the problem?

Question

#i write this code to calculate the BMI

def bmi_calculator(Weight,Hight):
Bmi = Weight/(Hight*2)
if Bmi < 18.5:
print("underweight")
elif Bmi >= 18.5 and Bmi < 25:
print("normal")
elif Bmi >= 25 and Bmi < 30:
print("overweight")
elif Bmi > 30:
print("obesity")
bmi_calculator(52,1.85)

#someone know thw solution?

Answer 1

Hey,
First of all, your formula is wrong.
The BMI is being calculated as the following:
BMI = (weight / height / height) * 10000

Or simplified:
BMI = (weight/height**2)* 10000

2) You should pass the height in centimeters to the function like 185 and not in meter like 1.85. Since 1.85 is basically ~2 and not 185, that's because of the dot. If you would like to pass meters you should change the formula to:

BMI = ((weight*100)/height**2)* 10000

Here is as example:

If you call the function with (52, 185), here is what happens:

BMI = (52 / 185**2)*10000
> BMI = 15.2
> underweight

I hope you understand it.

Answer 2

Thanks bro, i will try iy

Answer 3

Hey,

Your BMI formula is incorrect, as well as your function input. Here is the correct way of doing it:

def bmi_calculator(Weight,Hight):
Bmi = (Weight/(Hight**2)) * 10000

if Bmi > 30:
print("obesity")
elif Bmi >= 25:
print("overweight")
elif Bmi >= 18.5:
print("normal")
else:
print("underweight")

bmi_calculator(52, 185)
