When it comes to measurements, one of the most common challenges is converting between centimeters (cm) and inches (in). Different countries use different systems—some rely on the metric system (centimeters, meters, kilometers), while others use the imperial system (inches, feet, miles).
If you’ve ever asked yourself:
“How many inches is 70 cm?”
You’re in the right place. In this guide, we’ll break it down step by step, give you real-world examples, and make the conversion easy to understand.
Understanding the Basics: cm vs. inches
Before converting, let’s get clear on the two units:
- Centimeters (cm): Part of the metric system, used widely across the world.
- Inches (in): Part of the imperial system, mainly used in the United States and a few other countries.
The relationship between the two is simple:
- 1 inch = 2.54 cm
- 1 cm = 0.393701 inches
The Formula for Conversion
To convert centimeters into inches, use this formula:
Inches = Centimeters × 0.393701
This means that any centimeter value can be multiplied by 0.393701 to get the measurement in inches.
Converting 70 cm to Inches
Now, let’s apply the formula:
- 70 × 0.393701 = 27.5591 inches
- Rounded to two decimal places, 70 cm = 27.56 inches.
- So whenever you see 70 cm, think of it as just over 27 and a half inches.
Quick Approximation Method
If you don’t have a calculator, here’s a shortcut:
- Since 1 inch = 2.54 cm, simply divide cm by 2.54.
- 70 ÷ 2.54 = 27.56 inches
Both methods give you the same result.
What Does 70 cm Look Like in Real Life?
Sometimes, numbers are easier to understand when compared to everyday objects. Here are a few real-world examples of objects around 70 cm (27.5 inches) long:
- A standard baseball bat
- A small travel guitar
- A typical office desk height
- The width of a large computer monitor
- A flat-screen TV around 28 inches
This makes it easier to visualize how long 70 cm actually is.
