Unit conversion practice

What you will practise

Multiply when the factor states target units per source unit. Divide by the same factor to reverse the conversion.

source_amount * conversion_factor

The syntax above is a guide. Read the data and each task to choose the right arguments for your formula.

3 exercises in this lesson

1. Exercise 1 · answer in E10

   Convert the length in B9 to its target unit using conversion factor C9.

2. Exercise 2 · answer in E10

   Reverse the conversion: divide converted length D9 by factor C9.

3. Exercise 3 · answer in E10

   Convert total length across B2:B4 using the shared factor in C9.

Before you check your answer

• Keep the source data intact. Write your answer in the highlighted result cell. Changing a source value changes the question instead of solving it.
• Use the requested cells. Check the first and last row of a range and read its column heading. A plausible total can still come from the wrong data.
• Reference values that can change. A fixed number may match today's sheet. A cell reference keeps the formula connected when the source values change.

How the answer is checked

The workbook evaluates your formula against the requested result. It also checks the skill being practised and tests the formula with changed source data, so a fixed answer that happens to match is not enough.

Use progressive hints when you need help, then try the task again with fresh data. Correctly solving a step opens the next exercise.
