Question

Develop and test a Python program that converts pounds to grams, inches to centimeters, and kilometers to miles. The program should allow conversions both ways.

Answer 1

please go through screenshots for better understanding.Any comments below.Thank you.

python code:

def poundsTograms(pounds): #implementing pundsTograms method
grams = pounds /0.00220462 # calculating grams
return grams

def inchesTocm(inches): # implemeting inchesTocm method
cm = inches*2.54 #calculating centimeters
return cm

def kmTomiles(km): #implementing kmTomiles method
miles = km*0.621371 #calculating miles
return miles

def gramsTopounds(grams): #implementing gramsTopounds method
pounds = grams*0.00220462 #calculating pounds
return pounds

def cmToinches(cm): #implementing cmToinches method
inches = cm/2.54 # calculating inches
return inches

def milesTokm(miles): #implementing milesTokm method
km = miles/0.621371 #calculating kilometers
return km

#prompting user to enter option
c = int(input("enter optiion\n1.pounds to grams\n2.inches to centimeters\n3.kilometers to miles\n4.grams to pounds\n5.centimeters to inches\n6.miles to kilometers\n"))

if c==1:
p = float(input("enter pounds:")) #reading input from user
print(p," punds = ",poundsTograms(p)," grams") #printing result
  
elif c==2:
i = float(input("enter inches:"))#reading input from user
print(i," inches = ",inchesTocm(i)," cms") #printing result
  
elif c==3:
km = float(input("enter kilometers:"))#reading input from user
print(km," kilometers = ", kmTomiles(km)," miles") #printing result
  
elif c==4:
grams = float(input("enter grams:"))#reading input from user
print(grams,"grams = ",gramsTopounds(grams)," pounds") #printing result
  
elif c==5:
cm = float(input("enter centimeters:"))#reading input from user
print(cm," centimeters = ",cmToinches(cm)," inches") #printing result
  
elif c==6:
miles = float(input("enter miles:"))#reading input from user
print(miles," miles = ",milesTokm(miles)," kms") #printing result
else:
print("Invalid option")
