Prompt: A half-life is the amount of time it takes for a substance or entity to fall to half its original value. Caffeine has a half-life of about 6 hours in humans. Given caffeine amount (in mg) as input, output the caffeine level after 6, 12, and 24 hours. Use a string formatting expression with conversion specifiers to output the caffeine amount as floating-point numbers.

Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
print('{:.2f}'.format(your_value))

Ex: If the input is:

100
the output is:

After 6 hours: 50.00 mg
After 12 hours: 25.00 mg
After 24 hours: 6.25 mg

my code:
caffeine_mg = float(input())

six_hours = caffeine_mg / 2
twelve_hours = six_hours / 2
twenty_four_hours = twelve_hours / 4

print('After 6 hours: {:.2f}'.format(six_hours))
print('After 12 hours: {:.2f}'.format(twelve_hours))
print('After 24 hours: {:.2f}'.format(twenty_four_hours))

Question: How do I add "mg" at the end? This is my output
After 6 hours: 50.00
After 12 hours: 25.00
After 24 hours: 6.25
