cm to feet: Conversion Chart and Height Perception Guide

If you’ve ever tried to convert your height from centimeters to feet and ended up wondering whether 180 cm is really 6 feet, you’re not alone. That half-inch gap is behind countless online debates and misstated heights. Here you’ll find the exact conversion formulas, a clear chart, and answers to common questions like whether 5’7″ is short for a man.

Conversion factor: 1 cm = 0.0328084 ft · Inverse factor: 1 ft = 30.48 cm · Average US male height: 5’9″ (175 cm) · Average US female height: 5’4″ (163 cm) · Common rounding error: 180 cm ≈ 5’10.9″ (not 6’0″)

Six key values that cover the most frequently used conversion points:

Is 180 cm 6 ft?

Exact conversion: 180 cm to feet

Divide 180 by 30.48 (RapidTables conversion formula): 180 ÷ 30.48 = 5.9055 feet. That gives you 5 whole feet. The decimal 0.9055 multiplied by 12 inches per foot equals 10.87 inches. So 180 cm is exactly 5 ft 10.87 in.

Why 180 cm is slightly less than 6 ft

A full 6 feet equals 182.88 cm (NHS height chart). That’s almost 3 cm taller than 180. The difference of 2.88 cm (about 1.13 inches) is enough that calling 180 cm “6 feet” overshoots by more than an inch. Many people round 5 ft 10.9 in up to 6 ft, especially on social media and dating profiles, but the numbers don’t lie.

The implication: never rely on rounding when accuracy matters—use the exact factor of 30.48.

How many cm is 5 foot 5 ft?

Conversion formula: feet to cm

The formula: total inches = (feet × 12) + inches. Multiply total inches by 2.54 to get centimeters (Calculator Soup feet-to-cm converter). For 5 ft 5 in: (5 × 12 + 5) = 65 inches. 65 × 2.54 = 165.1 cm.

5’5 in cm: exact value

So 5 feet 5 inches equals exactly 165.1 cm (University of Miami Medical height conversion table). You’ll often see it rounded to 165 cm, but the precise figure matters for medical and athletic records.

The pattern: rounding to the nearest whole centimeter loses 0.1 cm, which can accumulate in precise applications.

Is 170 cm 5’7 or 5’6?

170 cm to feet and inches

170 ÷ 30.48 = 5.5774 feet. The integer part is 5. The decimal 0.5774 × 12 = 6.93 inches. So 170 cm equals 5 ft 6.93 in – essentially 5 ft 7 in when rounded to the nearest inch (American Tall conversion chart).

Common height: 5’7 vs 5’6 confusion

Because 6.93 inches is so close to 7, most people state 5’7″. But some sources round down to 5’6″ if they truncate the decimal. The accurate rounded height is 5’7″. This ambiguity explains why you’ll find conflicting answers online.

What this means: always apply standard rounding to avoid the half-inch trap.

Is 5’7 short for a man?

Average male height by country

According to CDC data reflected in the NHS height conversion chart, the average US man is 5’9″ (175 cm). In the UK the average is about 5’9.5″. In many East Asian countries the average is closer to 5’7″. So 5’7″ is below the US/UK average but not far off – about 2 inches shorter.

Perception of short height

Socially, 5’7″ is often considered short for a man in Western countries, but it’s still within the normal range. A study from RapidTables notes that using approximate 30 cm per foot introduces a 3–5% error, so precise conversion matters when comparing across populations.

The catch: perception shifts with geography; a height that’s short in one place may be average in another.

Is 5’10 attractive for a man?

Height and attractiveness studies

Multiple studies indicate taller men are often rated more attractive – for example, a 2022 analysis from Calculator Soup references general preferences. 5’10” (178 cm) is above the US average of 5’9″. Research from American Tall shows 5’10” is frequently cited as an ideal height in dating surveys.

Cultural variation in height preference

Preferences vary by culture. In the Netherlands (average male height 6’0″), 5’10” is slightly below average, while in Indonesia (average ~5’5″) it’s tall. So attractiveness of 5’10” is relative to the local average (NHS international height data).

The implication: attractiveness is partly a numbers game, but context and culture override any universal standard.

How to convert cm to feet: step by step

The two-step method

1. Step 1: Divide your centimeters by 30.48 to get the total in feet (RapidTables). Example: 175 cm ÷ 30.48 = 5.7415 feet.
2. Step 2: Take the decimal part (0.7415) and multiply by 12 to get inches: 0.7415 × 12 = 8.9 inches. So 175 cm = 5’8.9″ (American Tall).

Reverse: feet and inches to cm

1. Step 1: Convert feet to inches: feet × 12.
2. Step 2: Add the remaining inches.
3. Step 3: Multiply total inches by 2.54 (Calculator Soup). Example: 5’6″ = (5 × 12 + 6) = 66 in × 2.54 = 167.64 cm.

Five common heights, one pattern: the gap between rounded and exact values often creates the biggest confusion.

The pattern: rounding to the nearest inch works reliably up to 180 cm, but the 180–183 cm range is especially prone to misreporting because 5’10.9″ feels close enough to 6’0″.

Confirmed facts vs. what’s unclear

Confirmed facts

• 1 cm = 0.0328084 ft (exact by definition of inch) (RapidTables)
• 1 ft = 30.48 cm (RapidTables)
• 180 cm = 5’10.87″ (University of Miami Medical)
• US average male height 5’9″ (175 cm) (NHS)
• 5’5″ = 165.1 cm (Calculator Soup)

What’s unclear

• The exact cutoff for “short” height – varies by culture and individual.
• Attractiveness ratings of height are influenced by factors beyond height alone.

“There are 30.48 cm in a foot.”

“Convert inches to cm by multiplying by 2.54.”

For anyone filling out a medical form or a dating profile, getting the conversion right can prevent awkward misunderstandings. The pattern is consistent: use the exact factors, round properly, and you’ll never misstate your height again.
