5 Feet 6 Inches in cm: Exact Height Conversion

Guide 08-0116 · Updated · Step by step

5 feet 6 inches is exactly 167.64 centimeters. To convert, multiply the total inches (66) by 2.54, since one inch equals 2.54 cm. This height is commonly written as 168 cm in everyday use, but the precise figure is 167.64 cm.

Why 2.54 cm per Inch?

The inch is defined as exactly 2.54 centimeters by international agreement (the International Yard and Pound Agreement of 1959). This means the conversion is not an approximation but a fixed mathematical relationship. Before 1959, different countries used slightly different inch standards, but today the definition is universal. When you convert feet and inches to centimeters, you are using this exact factor, so the result is always precise to two decimal places.

How to Convert 5’6″ to cm Yourself

You can do the math in two quick steps:

  1. Convert feet to inches: 5 feet × 12 inches/foot = 60 inches.
  2. Add the remaining inches: 60 + 6 = 66 inches total.
  3. Multiply by 2.54: 66 × 2.54 = 167.64 cm.

If you want the result in meters, divide by 100: 1.6764 meters. For most practical purposes, rounding to 168 cm is fine, but for medical or scientific records, use 167.64 cm.

Why the Number Matters: Everyday Uses

Knowing your height in centimeters is essential for international travel, online shopping, and filling out forms in countries that use the metric system. For example, many European clothing size charts ask for height in cm, and bike frame sizes are often based on your height in cm. If you are 5’6″, you are around the average height for adult women in many countries (the global average is about 159 cm, but in the U.S. it is about 162 cm). For men, 5’6″ is below the global average of about 171 cm, but it is still a common height in parts of Asia and Latin America.

Common Mistakes When Converting

The most frequent error is forgetting to convert feet to inches first. Some people multiply 5.6 by 2.54, which gives 14.22 cm—a meaningless number. Another mistake is rounding too early: if you round 66 inches to 65 or 67, you get 165.1 or 170.18 cm, which is off by several centimeters. Always keep the exact total inches before multiplying. Also, note that 5’6″ is not the same as 5.6 feet; 5.6 feet would be 5 feet and 7.2 inches, which is about 170.7 cm.

Height Conversion Table: 5′ to 6′

Here is a quick reference for heights near 5’6″:

  • 5’4″ (64 in) = 162.56 cm
  • 5’5″ (65 in) = 165.10 cm
  • 5’6″ (66 in) = 167.64 cm
  • 5’7″ (67 in) = 170.18 cm
  • 5’8″ (68 in) = 172.72 cm

This pattern helps if you need to estimate other heights: each additional inch adds exactly 2.54 cm.

Metric vs. Imperial: Why Both Systems Exist

The United States, Myanmar, and Liberia are the only countries that still use the imperial system for everyday measurements. Most of the world uses centimeters and meters. This dual system means that height is often listed in both formats on passports, driver’s licenses, and medical records. For example, a U.S. passport application asks for height in feet and inches, but a visa form for many countries asks for centimeters. Understanding the conversion helps you fill out forms correctly without carrying a calculator.

Frequently Asked Questions

Is 5’6″ considered short for a man?

In the United States, the average adult male height is about 5’9″ (175 cm), so 5’6″ is below average. However, in many countries, such as Indonesia or the Philippines, 5’6″ is close to or above the average male height. Height perception varies by region and generation, so it is not universally “short.”

How many cm is 5’6″ in feet and inches?

It is exactly 167.64 cm. To get this, convert 5 feet to 60 inches, add 6 inches for 66 total, then multiply by 2.54. Some sources round to 168 cm, but the exact value is 167.64 cm.

What is 5’6″ in meters?

Divide 167.64 cm by 100 to get 1.6764 meters. For most uses, you can say 1.68 meters. This is useful for filling out European forms or comparing with height charts that use meters.

Why do some charts say 5’6″ is 167.6 cm instead of 167.64?

They are likely rounding to one decimal place. 167.64 cm rounded to one decimal is 167.6 cm. Both are correct, but the exact conversion is 167.64 cm. If you need precision for medical or scientific purposes, use the full two-decimal figure.

How do I convert my height from cm back to feet and inches?

Divide the cm by 2.54 to get total inches. Then divide by 12 to get feet, and the remainder is inches. For example, 167.64 cm ÷ 2.54 = 66 inches. 66 ÷ 12 = 5 feet with a remainder of 6 inches, so 5’6″.
