Ever found yourself scratching your head over a seemingly simple unit conversion like converting 70 cm to feet? Whether you're planning a trip where you'll need to understand local measurements, or just satisfying your curiosity, understanding how to swiftly convert centimeters to feet can save you time and frustration. In this article, we'll explore three simple tricks that make this conversion straightforward, ensuring you'll never be stumped by such units again.
Understanding the Basics
Before we dive into the tricks, let's understand the basic principle of metric to imperial conversion. Here's a quick refresher:
- 1 inch = 2.54 cm
- 1 foot = 12 inches
Thus, 1 foot = 30.48 cm
Trick #1: The Straightforward Calculation
The easiest, albeit somewhat time-consuming, method is to calculate the conversion by hand:
-
Convert centimeters to inches:
- Since 1 inch = 2.54 cm, you divide 70 cm by 2.54.
70 cm รท 2.54 cm/inch = 27.559 inches
-
Convert inches to feet:
- There are 12 inches in a foot, so divide the number of inches by 12 to find feet.
27.559 inches รท 12 inches/foot = approximately 2.2966 feet

Trick #2: The Quick Memorization Technique
For those who deal with measurements frequently, committing a couple of key figures to memory can speed up the process:
- 30 cm is about 1 foot (since 30.48 cm = 1 foot).
- 10 cm is about 4 inches
Now, to convert 70 cm:
- 70 cm is slightly more than 2 times 30 cm (since 70 > 60 cm, which is 2 feet).
- The remainder, which is 70 cm - (2 * 30 cm) = 10 cm, converts to 4 inches.
So, 70 cm = 2 feet and 4 inches.
