Python program to convert seconds to milliseconds

Milliseconds is a smaller unit of time used for problems where precise time calculations are desired. We can easily convert seconds to milliseconds using Python. This is useful in many applications, such as video editing, data analysis, and real-time processing.

Problem Description

We are given time input in seconds and have to convert it into milliseconds. In this problem, we are going to learn how we can convert seconds to milliseconds in Python.

The formula for converting seconds to milliseconds:

Milliseconds = Seconds × 1000

Examples

Input: 3
Output: 3000
Explanation:
We know that,
1 second = 1000 milliseconds, 
we calculate:
3 × 1000 = 3000 milliseconds

Input: 0.5
Output: 500
Explanation:
We know that,
1 second = 1000 milliseconds,
we calculate: 0.5 × 1000 = 500 milliseconds

Input: 0
Output: 0
Explanation:
We know that,
1 second = 1000 milliseconds,
we calculate: 0 × 1000 = 0 milliseconds

Converting Seconds to Milliseconds Using Direct Formula

In this approach, we use the direct formula to convert the given input of time in seconds to milliseconds. For converting seconds into milliseconds, we multiply the given seconds by 1000 because 1 second = 1000 milliseconds. After converting the unit of time in milliseconds, we print the output.

Steps for Implementation

• We take input of time in seconds units.
• Now we use the direct formula to convert seconds into milliseconds: milliseconds = Seconds × 1000.
• After applying the formula, we print the output using the print() function.

Implementation Code

seconds = 5
milliseconds = seconds * 1000
print(f"{seconds} seconds is equal to {milliseconds} milliseconds.")

Output

5 seconds is equal to 5000 milliseconds.

Space Complexity: O(1), constant space

Converting Seconds to Milliseconds Using Function

The logic of this approach is the same as the above approach. When we use a function, we can reuse the code any number of times. In this approach, we use a function which takes a parameter, seconds. Inside the function, we calculate the milliseconds using the formula: Milliseconds = Seconds × 1000. After calculating time in milliseconds, we print the output.

Steps For Implementation

• Create a function that takes seconds as the input parameter.
• Inside the function, use the formula to calculate milliseconds: Milliseconds = Seconds × 1000. This function returns milliseconds unit of time.
• Call the function and display the output.

Implementation Code

def convert_seconds_to_milliseconds(seconds):
    milliseconds = seconds * 1000
    return milliseconds

seconds = 3
result = convert_seconds_to_milliseconds(seconds)
print(f"{seconds} seconds is {result} milliseconds")

seconds = 0.5
result = convert_seconds_to_milliseconds(seconds)
print(f"{seconds} seconds is {result} milliseconds")

seconds = 5.4
result = convert_seconds_to_milliseconds(seconds)
print(f"{seconds} seconds is {result} milliseconds")

seconds = 0
result = convert_seconds_to_milliseconds(seconds)
print(f"{seconds} seconds is {result} milliseconds")

Output

3 seconds is 3000 milliseconds
0.5 seconds is 500.0 milliseconds
5.4 seconds is 5400.0 milliseconds
0 seconds is 0 milliseconds
