ParaphrasingConverting 5 2—commonly understood as 5 feet 2 inches—to centimeters is a straightforward process for height measurements. This imperial-to-metric conversion is essential for students, travelers, fitness enthusiasts, and professionals working across unit systems. Accurate conversions ensure consistency in medical records, clothing sizes, sports stats, and international standards.
Understanding the Units
The imperial system uses feet (ft) and inches (in), where 1 foot equals 12 inches. The metric system relies on centimeters (cm), with 1 inch precisely equaling 2.54 cm and 1 foot equaling 30.48 cm (12 * 2.54). These factors form the basis for reliable conversions, especially for human heights like 5 2, which totals 62 inches (5 * 12 + 2).
Conversion Formula
The formula to convert feet and inches to cm is:
Total cm = (feet × 30.48) + (inches × 2.54)
This method accounts for both components without converting everything to inches first, though both approaches yield identical results.
Step-by-Step Example: How to Convert 5 2 to cm
- Break down the measurement:5 feet and 2 inches.
- Convert feet to cm:5 × 30.48 = 152.4 cm.
- Convert inches to cm:2 × 2.54 = 5.08 cm.
- Add the results:152.4 + 5.08 =157.48 cm.
Thus, 5 2 equals exactly 157.48 cm. For quick mental math, approximate 1 foot as 30 cm and 1 inch as 2.5 cm: (5 × 30) + (2 × 2.5) = 150 + 5 = 155 cm, a close estimate refined by exact factors.
Practical Applications
Everyday use:Compare heights for travel (e.g., amusement park rides list limits in cm) or online shopping (European sizes use cm).

Common Mistakes to Avoid
- Forgetting inches: Converting only feet (5 ft ≈ 152 cm) understates by 5 cm.
- Unit confusion: Ensure "5 2" means feet/inches, not yards or meters.
- Rounding errors: Use at least two decimals for inches; 157.5 cm is a practical rounded value, but 157.48 cm is exact.
- Mixed systems: Double-check if input is already in cm.
