Unit conversion utilities in SciPy - Mini Project: Build & Apply

Unit Conversion Utilities with SciPy

📖 Scenario: Imagine you work in a lab where you often receive measurements in different units. You want to create a simple program to convert these measurements to a standard unit for easier analysis.

🎯 Goal: Build a Python program using SciPy constants to convert lengths from inches to centimeters.

📋 What You'll Learn

Create a list of length measurements in inches

Set a conversion factor from inches to centimeters

Use the SciPy conversion factor to convert all measurements to centimeters

Print the converted list of lengths in centimeters

💡 Why This Matters

🌍 Real World

Scientists and engineers often need to convert measurements between units to compare data or prepare reports.

💼 Career

Knowing how to handle unit conversions programmatically is useful for data analysts, scientists, and engineers working with measurement data.

1

Create a list of lengths in inches

Create a list called lengths_in_inches with these exact values: 5, 10, 15, 20, 25.

SciPy

# Create the list lengths_in_inches with the given values
# Your code here

Need a hint?

Use square brackets to create a list and separate values with commas.

2

Set the conversion factor from inches to centimeters

Import scipy.constants and create a variable called inch_to_cm set to scipy.constants.inch * 100.

SciPy

lengths_in_inches = [5, 10, 15, 20, 25]
# Import scipy.constants
# Set inch_to_cm = scipy.constants.inch * 100
# Your code here

Need a hint?

Import scipy.constants first, then assign inch_to_cm = scipy.constants.inch * 100.

3

Convert lengths from inches to centimeters

Create a new list called lengths_in_cm by multiplying each value in lengths_in_inches by inch_to_cm using a list comprehension.

SciPy

lengths_in_inches = [5, 10, 15, 20, 25]
import scipy.constants
inch_to_cm = scipy.constants.inch * 100
# Create lengths_in_cm by converting lengths_in_inches to centimeters
# Your code here

Need a hint?

Use a list comprehension to multiply each length by inch_to_cm.

4

Print the converted lengths in centimeters

Write a print statement to display the list lengths_in_cm.

SciPy

lengths_in_inches = [5, 10, 15, 20, 25]
import scipy.constants
inch_to_cm = scipy.constants.inch * 100
lengths_in_cm = [length * inch_to_cm for length in lengths_in_inches]
# Print lengths_in_cm
# Your code here

Need a hint?

Use print(lengths_in_cm) to show the converted list.
