Using this ratio, we can easily convert centimeters to inches by multiplying the length in centimeters by 0.393701.
How to Apply the Formula

4. Quick Mental Conversion for Rough Estimates
If you're not carrying a phone or an app, here's a simple trick for a quick approximation:

For 90 cm:
- 90 cm / 2.5 = 36 inches (which is a close estimate to our exact calculation)
Limitations and Usefulness
- Not Exact: This method isn't as precise as the exact formula but is great for a quick estimate when exact measurements aren't crucial.
