Introduction
Riya was filling out her sports registration form in school when she paused at the height section. “I’m 170 cm tall,” she thought, “but what’s that in feet and inches?” She looked around the classroom, confused, as her coach had asked everyone to mention their height in feet. If you’ve ever faced this confusion during form-filling, sports trials, or even casual conversations, you’re not alone. Understanding height conversions between centimeters and feet is a practical math skill that helps in real-life situations from medical forms to international applications. Let’s decode this conversion once and for all.
What is 170 cm in Feet?
170 centimeters equals approximately 5 feet 7 inches (5’7″).
This is the most accurate conversion. When you convert 170 cm using the standard formula, you get 5.577 feet, which translates to 5 feet and about 6.93 inches—essentially 5’7″.
Many people wonder if it’s 5’7″ or 5’8″, and the answer is clear: 170 cm is 5’7″, not 5’8″. The difference matters, especially when precision is required for medical records, sports eligibility, or official documentation.
Why This Confusion Exists
People often round up heights in casual conversation. Since 170 cm is close to 171 cm (which is nearer to 5’7.5″), some might casually say 5’8″. However, mathematically and officially, 170 cm is 5’7″.
Understanding the Conversion Formula
To convert centimeters to feet and inches, you need to understand the basic units:
Conversion Facts:
- 1 inch = 2.54 centimeters
- 1 foot = 12 inches
- 1 foot = 30.48 centimeters
The Formula:
Feet = Centimeters ÷ 30.48For converting to feet and inches separately:
Total inches = Centimeters ÷ 2.54
Feet = Total inches ÷ 12 (whole number part)
Remaining inches = Total inches % 12 (remainder)This simple division helps you convert any height measurement from the metric system to the imperial system used in countries like the United States.
Step-by-Step Conversion Process
Let’s convert 170 cm to feet and inches step by step:
Method 1: Direct Feet Conversion
- Divide 170 by 30.48
- 170 ÷ 30.48 = 5.577 feet
- Separate the whole number (5 feet)
- Multiply the decimal by 12 to get inches
- 0.577 × 12 = 6.93 inches
- Result: 5 feet 7 inches
Method 2: Convert to Inches First
- Divide 170 by 2.54
- 170 ÷ 2.54 = 66.93 inches
- Divide total inches by 12
- 66.93 ÷ 12 = 5.577
- Take the whole number as feet: 5 feet
- Multiply remainder by 12
- 0.577 × 12 ≈ 7 inches (rounded)
- Result: 5 feet 7 inches
Both methods give you the same answer. Choose whichever feels easier to calculate!
Quick Reference Table for Heights

Keep this table handy for quick reference during exam problems or form-filling situations!
Common Mistakes Students Make
1. Confusing Decimal Feet with Inches
Students often see “5.7 feet” and think it means 5’7″. Wrong! 5.7 feet actually means 5 feet and 0.7 of a foot, which equals 5’8.4″.
Example:
- Correct: 170 cm = 5.577 feet = 5’7″
- Incorrect: 5.7 feet ≠ 5’7″
2. Rounding Too Early
Rounding numbers before completing the calculation leads to incorrect results. Always round at the final step.
3. Using Wrong Conversion Factors
Mixing up 2.54 (cm per inch) with 30.48 (cm per foot) creates errors. Double-check which unit you’re converting to.
4. Forgetting to Separate Feet and Inches
When converting to feet and inches, students sometimes forget to separate the decimal into feet and the remaining inches.
5. Adding Instead of Multiplying Decimal
After getting feet as a whole number, multiply the decimal by 12 (not add) to get inches.
Easy Tricks to Remember Conversions
Trick 1: The “30-12” Method
Remember: 30 cm ≈ 1 foot (actually 30.48, but 30 is easier)
For 170 cm:
- 170 ÷ 30 = 5.67 feet
- This gives you approximately 5’7″ quickly
Trick 2: The “2.5 Rule”
2.5 cm ≈ 1 inch (actually 2.54, but easier to remember)
For 170 cm:
- 170 ÷ 2.5 = 68 inches
- 68 ÷ 12 = 5 feet 8 inches (approximate)
Trick 3: Memorize Common Heights
Simply memorize these benchmarks:
- 150 cm = 4’11”
- 160 cm = 5’3″
- 170 cm = 5’7″
- 180 cm = 5’11”
Everything else can be estimated from these reference points!
Trick 4: The “Add 3” Pattern
For every 3 cm above 170:
- 170 cm = 5’7″
- 173 cm = 5’8″
- 175 cm = 5’9″
- 178 cm = 5’10”
This pattern helps with quick mental conversions.
