What is 173 cm in feet and inches?

Exact conversion of 173 cm to feet and inches

The precise answer: 173 centimeters equals 5 feet 8.11 inches — or 5.6759 feet in decimal form. That’s 68.11 inches total. These numbers come from the standard conversion factors: 1 foot = 30.48 cm and 1 inch = 2.54 cm, as defined by the University of Manchester’s conversion reference.

Here’s the math: 173 ÷ 30.48 = 5.6759 feet. The whole number (5) is the feet. The decimal (0.6759) multiplied by 12 gives 8.11 inches. That’s how you get 5 feet 8.11 inches — confirmed by Calculatio’s conversion tool and the height converter from The Calculator Site.

Why 173 cm is often written as 5’8″ (and not 5’9″)

The decimal 0.6759 feet multiplied by 12 gives 8.11 inches. Since 8.11 is closer to 8 than to 9, rounding to the nearest whole inch yields 5’8″. A Perinatal.org.uk height conversion table (a medical reference) places 5’8″ at 172.7 cm and 5’9″ at 175.3 cm — confirming that 173 cm sits just above the 5’8″ mark. So 5’8″ is the correct rounded value, not 5’9″.

Why does 173 cm appear as both 5’6″ and 5’8″?

Rounding differences in sports (boxing, UFC)

If you’ve seen a fighter listed at 5’6″ and wondered how that squares with 173 cm, the answer is floor rounding. In combat sports like boxing and UFC, height is often reported by rounding down to the nearest inch — a practice that drops 5’8.11″ to 5’6″ if the organization uses a whole-foot truncation method. A Reddit r/tall community discussion notes that this kind of metric-to-imperial conversion often uses subtraction from nearby foot markers, which can introduce errors.

Conversion errors from using approximate formulas

Some calculators round 173 cm to 5.7 feet (as Symbolab’s converter does), while others show 5.68 feet. The difference comes from whether the tool rounds the decimal to one or two places. The underlying value — 5.675853 feet — is the same. The Omni Calculator height converter explains that the decimal part should be rounded down to get whole feet first, then multiplied by 12 to get inches. When that rule is applied, 173 cm always lands at 5’8″.

“In sports listings, 173 cm often appears as 5’6″ because the decimal portion is dropped entirely, not rounded.” — Reddit r/tall user

The implication: the same measurement can look three different ways depending on the context, but the underlying number never changes.

Why does 173 cm appear as both 5’6″ and 5’8″?

Rounding differences in sports (boxing, UFC)

In combat sports, height listings often use floor rounding — dropping the decimal entirely. A fighter who measures 173 cm (5’8.11″) may be listed at 5’6″ if the organization rounds down to the nearest whole foot. This is not a conversion error; it’s a convention. The Reddit r/tall community has documented how metric-to-imperial height conversion in sports often uses subtraction from nearby foot markers, which can produce inconsistent results.

Conversion errors from using approximate formulas

Some online tools use a shortcut: divide by 30, round to the nearest foot, then multiply the remainder by 12. If the tool rounds the feet value to the nearest integer before converting the remainder, 173 cm can appear as 5’6″ instead of 5’8″. The Omni Calculator team explains that the correct method is to keep the decimal, multiply by 12, and only then round the inches. Skipping that step is what creates the 5’6″ ghost.

Regional variations in average height

One number, many contexts. Here’s how 173 cm stacks up against official averages from different regions:

The pattern: 173 cm is a “tweener” height — above average in most of the world, slightly below in Western Europe and North America. For a man, it’s unremarkable in the US but tall in Asia. For a woman, it’s tall almost everywhere.

Height attractiveness and social perception

How to convert 173 cm to feet manually

Step-by-step conversion method

You don’t need a calculator — just two numbers and a little multiplication. Here’s the method used by The Calculator Site’s height converter:

1. Divide centimeters by 30.48 to get total feet. 173 ÷ 30.48 = 5.6759 feet.
2. Take the whole number (5) as the feet value.
3. Multiply the decimal (0.6759) by 12 to get inches. 0.6759 × 12 = 8.11 inches.
4. Combine: 5 feet 8.11 inches. Round the inches to the nearest whole number for everyday use: 5’8″.

For the reverse conversion — feet and inches to centimeters — multiply the feet figure by 12, add the inches, then multiply the total by 2.54.
