Pressure Unit Converter

Write a Python program to convert pressure in kilopascals to pounds per square inch,a millimeter of mercury (mmHg) and atmosphere pressure.

Pictorial Presentation:

Sample Solution-1:

Python Code:

# Prompt the user to input pressure in kilopascals and convert it to a floating-point number.
kpa = float(input("Input pressure in kilopascals: "))

# Convert kilopascals to pounds per square inch (psi) using the conversion factor.
psi = kpa / 6.89475729

# Convert kilopascals to millimeters of mercury (mmHg) using the conversion factor.
mmhg = kpa * 760 / 101.325

# Convert kilopascals to atmospheres (atm) using the conversion factor.
atm = kpa / 101.325

# Print the pressure in pounds per square inch (psi) with 2 decimal places.
print("The pressure in pounds per square inch: %.2f psi"  % (psi))

# Print the pressure in millimeters of mercury (mmHg) with 2 decimal places.
print("The pressure in millimeters of mercury: %.2f mmHg" % (mmhg))

# Print the atmosphere pressure (atm) with 2 decimal places.
print("Atmosphere pressure: %.2f atm." % (atm))

Sample Output:

Input pressure in in kilopascals> 12.35                                                                       
The pressure in pounds per square inch: 1.79 psi                                                              
The pressure in millimeter of mercury: 92.63 mmHg                                                             
Atmosphere pressure: 0.12 atm.

Sample Solution-2:

Python Code:

# Prompt the user to input the pressure in kilopascals and store it as a floating-point number.
kpa = float(input("Input the pressure in kilopascals > "))

# Calculate the pressure in pounds per square inch (psi) and round it to 3 decimal places.
pressure_in_psi = round(kpa * 0.145038, 3)

# Calculate the pressure in millimeters of mercury (mmHg) and round it to 3 decimal places.
pressure_in_mmHg = round(kpa * 7.50062, 3)

# Calculate the pressure in standard atmospheres (atmp) and round it to 3 decimal places.
pressure_in_atmp = round(kpa * 0.0098692382432766, 3)

# Display the calculated pressure values in psi, mmHg, and atmp using an f-string.
print(f"Pressure = {pressure_in_psi} psi \nor {pressure_in_mmHg} mmHg \nor {pressure_in_atmp} atmp")

Sample Output:

Input the pressure in kilopascals >  12.35
Pressure = 1.791 psi 
or 92.633 mmHg 
or 0.122 atmp
