5’6 in cm: Exact Conversion and Height Comparison Guide

If you’ve ever jotted down “5’6” on a form and wondered what that means for the rest of the world, the imperial‑to‑metric conversion is one of those small maths puzzles that pops up in travel, health screenings, and online shopping. Here’s the exact answer: 5 feet 6 inches equals 167.64 cm, a figure that sits just above the average U.S. woman’s height and well below the global male average.

5’6 in centimeters: 167.64 cm ·
5’6 in meters: 1.6764 m ·
Average U.S. female height: 5’4 (162.56 cm) ·
Average U.S. male height: 5’9 (175.26 cm) ·
Classification for women globally: Tall in many regions ·
Ideal weight at 170 cm (approx. 5’7): 53–72 kg (WHO)

Six key facts, one pattern: the difference of even one inch (2.54 cm) can push a person across important thresholds — from “average” to “tall” in some regions, or from normal BMI to overweight.

The implication: 5’6 sits at a meaningful inflection point — above the average woman in most Western countries, below the average man, and clearly tall in much of East Asia.

What is 5’6″ in cm?

The exact conversion of 5 feet 6 inches to centimetres is 167.64 cm. To understand how we get there, let’s break down the calculation.

The exact conversion formula

1. Convert feet to inches: 5 feet × 12 inches/foot = 60 inches (BYJU’S foot definition).
2. Add the remaining inches: 60 + 6 = 66 inches total.
3. Multiply total inches by 2.54 (the fixed conversion factor): 66 × 2.54 = 167.64 cm (Inch Calculator inch‑to‑cm conversion).

That’s the precise, mathematically exact result. The same formula applies for any height: (feet × 30.48) + (inches × 2.54).

Three adjacent values, one clear step: each extra inch adds exactly 2.54 cm.

The pattern: 5’6 is exactly midway between 5’5 and 5’7, and each step reflects the immutable 2.54 cm per inch. For anyone tracking growth or comparing heights internationally, this chart eliminates guesswork.

This makes 5’6 an easy reference point for all height conversions.

Is 170 cm 5’7″ or 5’6″?

This is one of the most common point of confusion in height conversion. 170 cm is not 5’6 — it’s a hair under 5’7.

Why 170 cm is closer to 5’7″ than 5’6″

Using the reverse formula: divide 170 by 2.54 to get 66.93 inches. Then subtract 60 inches (5 feet) to leave 6.93 inches. So 170 cm = 5 feet 6.93 inches, which rounding conventions normally call 5’7″ (The Calculator Site height chart).

Many sources round 170 cm up to 5’7″ because the extra 0.93 inches is so close to a full inch. The exact 5’6″ cutoff is 167.64 cm, so 170 cm is over 2 cm taller.

Common cm-to-feet conversion mistakes

• 167 cm ≈ 5’5.75″ (often rounded to 5’6″) — not the same as 5’6 exactly.
• 170 cm = 5’6.93″ — do not confuse with 5’6.
• 175 cm = 5’8.9″ — often listed as 5’9.

The trade-off: rounding can mislead — a 170 cm person who claims 5’7 is correct by convention, but a 167 cm person claiming 5’6 is also correct. The difference of 3 cm may change how a height is classified in clinical or fitness contexts.

Is 5-6 in cm tall?

Whether 5’6 (167.64 cm) is tall depends entirely on who you’re comparing against. In global terms, it’s above average for women and below average for men.

5’6 in centimeters and meters

5’6 is 167.64 cm or 1.6764 m. For quick reference, many consumer charts round 1.68 m (The Calculator Site conversion).

Comparing 5’6 to average heights

• Global average male height: about 5’9″ (175 cm) — NCBI global height data
• U.S. average male height: 5’9″ (175.26 cm) — CDC National Health Statistics
• U.S. average female height: 5’4″ (162.56 cm) — same CDC report

At 5’6, a woman in the U.S. is 2 inches taller than average, while a man is 3 inches shorter than average. In regions like Southeast Asia where average female height is around 5’0 to 5’2, 5’6 is clearly tall.

The implication: 5’6 is a “tallish” height for women in most countries, but not exceptionally so. For men, it is below average nearly everywhere outside of parts of South and Southeast Asia.

Is 5-6 tall for a girl?

This question often comes from parents, teens, and women themselves. The answer shifts by country, generation, and cultural context.

Height perceptions by country

• United States: Average woman is 5’4″ (162.56 cm). 5’6 is above average but common — about 30% of women are 5’6 or taller (CDC report).
• United Kingdom: Average woman is 5’3.6″ (161.6 cm) — 5’6 is similarly above average (NCBI UK height study).
• Many Asian countries: Average female height ranges from 4’11″ (150 cm) in some parts of Indonesia to 5’2″ (158 cm) in Japan. 5’6 is notably tall.

What is considered tall globally?

A woman at the 90th percentile for height in her country is generally considered tall. In the U.S., that threshold is about 5’6.5″. So 5’6 lands right at the edge. In countries with shorter averages, the same height puts a woman above the 95th percentile.

The catch: “tall” is a social label, not a clinical one. Whether it’s an advantage or a concern depends on the person and their environment. For sports like volleyball or modelling, 5’6 is often seen as moderate, not tall. While height can be a factor in certain professions, it’s important to remember that medical conditions like lung cancer have their own specific survival rates by stage, which you can explore at $lung cancer survival rates by stage.

Is 70 kg okay for 170 cm?

This ties weight to the 5’6 discussion because many people converting from 5’6 also ask about healthy weight. While the question uses 170 cm, it’s directly relevant — 5’6 (167.64 cm) is close enough that the same principles apply.

BMI = weight (kg) ÷ height (m)². At 170 cm and 70 kg: BMI = 70 ÷ (1.7 × 1.7) = 70 ÷ 2.89 = 24.2. The World Health Organization classifies a BMI of 18.5–24.9 as normal weight, so 24.2 is healthy but near the upper limit.

Using the standard BMI boundaries, a healthy weight for 170 cm is about 53–72 kg (NHS BMI guidance). For someone at 5’6 (167.64 cm), the range is roughly 52–70 kg.

However, BMI does not account for muscle mass, bone density, or fat distribution. An athlete at 70 kg and 170 cm may have a “normal” BMI but be very lean; a sedentary person at the same numbers might carry more body fat.

The trade-off: use BMI as a starting point, not a verdict. Waist measurement and body composition give a more complete picture of health risks.

The confirmed facts provide a solid foundation while the uncertainties highlight the need for contextual evaluation.

“Body mass index is a simple index of weight-for-height that is commonly used to classify underweight, overweight, and obesity in adults.”

For anyone navigating health forms, travel, or international sizing, the choice is clear: commit the 167.64 cm figure to memory, use the multiplication formula for any other height, and remember that 5’6 puts you at an interesting intersection — above average for women, below for men, and always exactly 66 inches tall.
