5 Foot 10 in cm: Exact Conversion and Common Questions

You’ve probably asked yourself how tall someone who’s 5 foot 10 really is in centimeters—maybe for a passport form, a dating app, or just out of curiosity. The answer is 177.8 cm, a figure that sits right around the average height for men in the United States but well above average for women. This guide breaks down the exact conversion, common rounding mix-ups, and where 5′10″ fits in global height standards.

5′10″ in cm: 177.8 cm · US male avg: 5′9″ (175.3 cm) · US female avg: 5′4″ (162.6 cm) · Common rounding: 178 cm often labeled 5′10″

Six key conversions, one pattern: the difference of a single inch or centimeter can change the label entirely.

What height is 5ft 10 in cm?

The exact conversion of 5′10″ to centimeters

5 ft 10 in equals exactly 177.8 centimeters. That value comes from the standard conversion factors used by every major calculator: one foot equals 30.48 cm (SplashLearn (educational math resource)) and one inch equals 2.54 cm (RapidTables (educational reference)).

Step-by-step calculation using the formula

• Step 1: Convert feet to inches: 5 ft × 12 = 60 in.
• Step 2: Add the remaining inches: 60 + 10 = 70 in total.
• Step 3: Multiply total inches by 2.54: 70 × 2.54 = 177.8 cm.

BYJU’S (online learning platform) demonstrates the same calculation: [(5×12)+10] × 2.54 = 70 × 2.54 = 177.8 cm (BYJU’S (K‑12 educational resource)).

Why 177.8 cm is the precise value

The number 177.8 is not a rounded estimate—it’s the product of two fixed international definitions. The foot is defined as exactly 30.48 cm, and the inch as 2.54 cm. When you apply those to 70 total inches, the result is mathematically exact. For reference, 5 ft alone gives 152.4 cm (Math Salamanders (primary math reference)) and 10 inches alone gives 25.4 cm (Math Salamanders). Summed they are 177.8 cm.

Is 178 cm 5′8″ or 5′10″?

178 cm is actually 5′10.08″ — close to 5′10″

178 cm converts to 70.08 inches, or 5 ft 10.08 in (Inch Calculator). That extra 0.08 in is about 2 mm, so it’s practically 5′10″ for most purposes. The confusion arises because 178 cm is only 0.2 cm above the true 177.8 cm of 5′10″—yet it’s often mistaken for 5′8″ by people who misremember the formula.

Common rounding: 177.8 cm vs 178 cm

When a height chart lists “178 cm” next to “5′10″,” it’s rounding up. The exact boundary for 5′10″ is 177.8 cm. Heights that fall between 177.8 cm and 180.3 cm are all sometimes called 5′10″ in casual contexts, even though 180 cm is actually 5′10.87″ (Math Salamanders).

How other borderline heights are labeled (177 cm, 180 cm)

177 cm equals 5′9.69″ and is often rounded to 5′10″ in everyday use. 180 cm (5′10.87″) is most commonly called 5′11″ (Inch Calculator). The pattern: people tend to round up to the next whole inch when the decimal exceeds 0.5, but the exact rule varies by region and context.

The implication: If you see a listing that says “178 cm = 5′10″,” it’s accurate enough for daily life, but for precise applications (military, aviation, modeling) you should use the raw number.

How tall is a 168 cm person?

168 cm in feet and inches = 5′6.14″

168 cm divided by 2.54 gives 66.14 inches, which is 5 ft 6.14 in (RapidTables). Most people round that to 5′6″. This height is near the average for women in many countries and a bit below the US female average of 5′4″ (162.6 cm).

Model height requirements for 168 cm

In commercial modeling, a minimum of about 173 cm (5′8″) is typical for runway work (CDC NCHS (height reference data)). At 168 cm, a woman would be below that threshold, though catalog and digital modeling sometimes accept shorter heights. For men, 168 cm is well below the average of 5′9″ (175.3 cm) and would not meet most professional requirements.

Comparison: 168 cm vs average heights

168 cm is about 5.4 cm taller than the US female average but 7.3 cm shorter than the US male average. In the Netherlands, where the average man stands 6′0″ (182.9 cm), a 168 cm person would be considered short in any gender context.

Is 5′10″ tall for a woman?

Average female height in the US and globally

The CDC reports that the average US woman aged 20+ is 63.7 in (162.6 cm) (CDC National Center for Health Statistics (U.S. health authority)). At 5′10″ (177.8 cm), a woman would be 15.2 cm taller than average—that’s roughly the same gap as a 6′2″ man compared with the average man.

Perception of tall: US vs other countries

In the United States, a 5′10″ woman is above the 95th percentile, meaning fewer than 5 women in 100 reach that height. In the Netherlands, where the average woman is about 5′7″ (170 cm), 5′10″ is still tall but not as rare. In parts of East Asia where female averages hover around 5′2″ (157 cm), 5′10″ would be extremely uncommon.

How 5′10″ compares to modeling standards

High‑fashion runway agencies typically look for women between 5′8″ and 6′0″. At 5′10″, a woman would be well within the desirable range—tall enough to fit sample garments without being so tall that she stands out on group casts. Commercial print and catalog modeling also favor 5′9″ to 5′11″ for women.

What height is considered tall in the US and the world?

US tall threshold: 5′11″ for men, 5′7″ for women

Based on the CDC NHANES data, the 85th percentile for US men is about 5′11″ and for US women about 5′7″ (CDC NCHS). That means if you’re a man at 5′10″, you’re tall but not distinctly above the 85th percentile. For women, 5′10″ blows past the threshold comfortably.

Global tall thresholds: Netherlands vs East Asia

In the Netherlands, the average male height is 6′0″ (182.9 cm), so “tall” really starts above 6′2″. In Japan or South Korea, where the average male height is about 5′7″ (170 cm), a 5′10″ man would be considered tall. 5′10″ is above average for men in the vast majority of countries, including the US, UK, Australia, and most of Latin America.

How 5′10″ fits into these categories

For a man, 5′10″ is above the US average (5′9″) but not universally labeled “tall.” For a woman, 5′10″ is tall in almost any country, often falling into the top 5–10% of the population. The label shifts with geography, but the measurement stays the same: 177.8 cm.

Height comparison: 5′10″ and common borderline values

The pattern: rounding conventions can shift a label by more than an inch, so always check the exact centimeter value.

The implication: Whether you are 5′10″ or one of these nearby heights, the label you see on a chart depends as much on rounding rules as on the actual measurement.

Confirmed facts versus what remains unclear

Confirmed facts

• 5′10″ = 177.8 cm (exact by international definition)
• 1 ft = 30.48 cm, 1 in = 2.54 cm
• US average male height: 175.3 cm (5′9″)
• US average female height: 162.6 cm (5′4″)
• 178 cm = 5′10.08″ (very close to 5′10″)
• 180 cm = 5′10.87″ (commonly called 5′11″)
• 168 cm = 5′6.14″

What’s unclear

• Exact rounding conventions: “178 cm → 5′10″” is common but not official; some charts round differently.
• Whether “tall” thresholds vary by specific demographic subgroups (age, ethnicity, socioeconomic status) beyond the broad averages.

Expert perspectives on height conversion

“The height 5′10″ in centimeters equals 177.8 cm. To convert 5 ft 10 in to centimeters, convert 5 feet to 60 inches, add 10 inches to get 70 inches, then multiply by 2.54 to get 177.8 cm.”

— Inch Calculator (height conversion tool)

“The U.S. CDC’s 2015‑2016 NHANES data reports the average height of men aged 20 and over as 69.1 inches (175.3 cm) and of women as 63.7 inches (162.6 cm).”

— CDC National Center for Health Statistics (U.S. health authority)

“One foot equals 12 inches and one inch equals 2.54 centimeters.”

What this means for you

If you’re 5′10″, you’re exactly 177.8 cm—a height that sits above the average man in the US and well above the average woman. Whether that counts as “tall” depends on your gender and where you live, but the conversion itself is rock‑solid. For a man in the United States, the choice is clear: 5′10″ puts you above the median, but don’t be surprised if you’re not considered “tall” until you hit 6′0″. For a woman, 5′10″ is a definite advantage in contexts where height is valued, such as sports or modeling.
