The Math: Breaking Down the Conversion
To fully understand the conversion of 5 foot 8 inches to centimeters, it is helpful to look at the exact mathematical formula used to switch between the imperial and metric systems.
Here is the step-by-step math to convert your height:
-
Convert feet to inches: There are exactly 12 inches in one foot. Multiply 5 feet by 12, which gives you 60 inches.
-
Add the remaining inches: Add the remaining 8 inches to the 60 inches. Your total height in inches is 68 inches.
-
Multiply by the metric conversion factor: The international standard dictates that one inch equals exactly 2.54 centimeters. Multiply 68 by 2.54.
This calculation reveals that 5 feet 8 inches in cm equals exactly 172.72 cm.
Common Mistakes in Height Conversion
When converting 5 ft 8 in to cm, many people make mathematical errors that skew their results. Watch out for these common pitfalls:
-
Confusing decimal feet with feet and inches: Some calculators will output 5.66 feet. Many mistakenly read this as 5 feet 6 inches, but 5.66 feet is actually 5 feet 8 inches.
-
Using 2.5 instead of 2.54: Some people use 2.5 as a mental shortcut for inches to centimeters. For a 68-inch person, this shortcut artificially reduces their height to 170 cm, stripping away over an inch of actual height. Always use 2.54.

How to Measure Your Height Accurately
Knowing what is 5 ft 8 in cm is only helpful if your baseline measurement is completely accurate. Many people inadvertently add or subtract an inch due to poor posture.
Follow these steps for an accurate home measurement:
-
Measure in the morning: Gravity compresses the cartilage in your spine throughout the day. You are typically 1 to 2 centimeters taller right out of bed.
-
Stand flat against a wall: Avoid standing on thick carpets or rugs. Stand on a hard floor with your heels, buttocks, shoulders, and the back of your head gently touching a flat wall without baseboards.
-
Use the book method: Place a hardback book flat on top of your head, ensuring it forms a perfect 90-degree angle with the wall. Mark the bottom of the book lightly with a pencil.
-
Measure the distance: Step away and use a stiff metal tape measure to record the exact distance from the floor to the pencil mark.
