Height Conversion Calculators
Enter feet and inches below to convert height into centimeters instantly.
If you’ve ever had to enter your height on a medical form, a fitness app, or an international registration page, you’ve probably hit the same snag: the form wants centimeters, but you think in feet and inches. And yes, being off by even a couple of centimeters can matter in health records, gear sizing, or travel paperwork.
In this guide, we’ll convert 5’7″ in cm accurately, show the exact math (so you can trust the result), and give you quick shortcuts and a printable-friendly reference table for nearby heights.
The exact conversion of 5 feet 7 inches to centimeters is:
This uses the international standard: 1 inch = 2.54 cm (exact).
Depending on what you’re filling out, you may not need all digits.
A good rule: if a form allows decimals, we’ll use 170.2 cm: if it’s a simple dropdown or single field, 170 cm is usually acceptable.
To convert centimeters to meters, we divide by 100:
For most everyday uses (like height settings in apps), 1.70 m is a common rounded entry, but 1.7018 m is the exact value.
When we understand the steps, we’re less likely to mis-enter height on important forms.
There are 12 inches in 1 foot.
Now we add the extra inches:
Using 1 in = 2.54 cm:
That’s how we get the exact metric height.
If we want a faster “one-line” method, we can convert feet directly to centimeters:
So for 5’7″:
This formula is handy when we’re converting a lot of heights quickly.
| Height (ft/in) | Inches Total | Exact cm | Rounded (nearest 0.5 cm) | Rounded (nearest cm) | Meters (exact) |
|---|---|---|---|---|---|
| 5’4″ | 64 | 162.56 | 162.5 | 163 | 1.6256 |
| 5’5″ | 65 | 165.10 | 165.0 | 165 | 1.6510 |
| 5’6″ | 66 | 167.64 | 167.5 | 168 | 1.6764 |
| 5’7″ | 67 | 170.18 | 170.0 | 170 | 1.7018 |
| 5’8″ | 68 | 172.72 | 172.5 | 173 | 1.7272 |
| 5’9″ | 69 | 175.26 | 175.5 | 175 | 1.7526 |
| 5’10” | 70 | 177.80 | 178.0 | 178 | 1.7780 |
Tip for printing: if you’re pasting this into a document, keep the columns Height, Exact cm, Rounded cm, Meters for a clean one-page checklist.
On FeetToMetersCalculator.com, we enter height exactly as:
That keeps the units unambiguous (and avoids the “5.7 ft” problem).
The exact conversion of 5’7″ in cm is 170.18 cm. This uses the international standard conversion factor of 1 inch = 2.54 cm (exact). Since 5’7″ equals 67 total inches, 67 × 2.54 = 170.18 cm.
Convert feet to inches first: 5 × 12 = 60 inches. Add the remaining inches: 60 + 7 = 67 inches. Then convert inches to centimeters using 2.54: 67 × 2.54 = 170.18 cm. Round only at the end if needed.
Use 170.18 cm when precision matters or decimals are allowed (medical records, research, body tracking). Use 170.2 cm for one-decimal fields in fitness apps. If a form only accepts whole numbers or dropdowns, 170 cm is typically the best rounded entry.
5’7″ equals 170.18 cm, which is 1.7018 meters because you divide centimeters by 100. Many apps or profiles accept 1.70 m as a clean rounded value, but 1.7018 m is the exact conversion when accuracy is important.
5’7″ means 5 feet plus 7 inches, but 5.7 feet means 5 feet plus 0.7 of a foot. Since 0.7 × 12 = 8.4 inches, 5.7 ft equals 5’8.4″—so the cm value will be taller than 5’7″ (170.18 cm).
It’s fine for a rough estimate, but it’s noticeably off for forms. Using 2.5 cm per inch gives 67 × 2.5 = 167.5 cm, while the exact value is 170.18 cm. That’s a 2.68 cm difference, which can affect sizing or health metrics.
