What is 5’5″ in cm?
Five foot five inches equals 165.1 centimeters. This conversion is consistent across every reputable calculator, educational platform, and official chart. The UHSussex NHS height conversion chart lists 5’5″ as 1.65 meters, which rounds to 165 cm when expressed without decimals. Independent tools like Inch Calculator and RapidTables both confirm the precise value of 165.1 cm.
Conversion formula
The universal formula for converting feet and inches to centimeters is: cm = 30.48 × ft + 2.54 × in. For 5’5″, plug in 5 feet and 5 inches: 30.48 × 5 + 2.54 × 5 = 152.4 + 12.7 = 165.1 cm. Unitarium explains this as an alternative: cm = 2.54 × (12 × ft + in), which gives 2.54 × 65 = 165.1 cm.
Using a height chart
SplashLearn provides a comprehensive chart showing how each additional foot converts: 1 ft = 30.48 cm, 2 ft = 60.96 cm, 3 ft = 91.44 cm, 4 ft = 121.92 cm, and 5 ft = 152.40 cm. Adding the 5 extra inches gives you 165.1 cm total.
The US foot was defined as exactly 0.3048 meters in 1959, and the conversion factor of 30.48 cm per foot has been stable ever since. That consistency means 5’5″ will always equal 165.1 cm—no rounding ambiguity from the formula itself.
How to convert 5 foot 5 inches to cm?
Converting 5 foot 5 to cm requires two simple multiplication steps. First, multiply 5 feet by 30.48 to get 152.4 cm. Then multiply 5 inches by 2.54 to get 12.7 cm. Add them together: 152.4 + 12.7 = 165.1 cm.
Step-by-step calculation
The step-by-step method breaks the conversion into three stages:
- Convert feet to inches: 5 × 12 = 60 inches
- Add remaining inches: 60 + 5 = 65 total inches
- Multiply total inches by 2.54: 65 × 2.54 = 165.1 cm
Calculator Soup demonstrates this same method with worked examples.
Online tools and charts
If you prefer not to do the math manually, use any online height converter. The Calculator Site and Inch Calculator both provide instant results. For a visual reference, the NHS height chart (published March 2023) displays 5’5″ as 1.65 meters.
Is 165 cm 5’5″ or 5’4″?
One hundred sixty-five centimeters is 5’5″ when rounded, but the precise value is 165.1 cm. The difference matters for exact conversions: 5’4″ equals 162.56 cm, while 5’5″ equals 165.1 cm. That means 165 cm falls between the two, closer to 5’5″.
Exact equivalents
5’5″ = 165.1 cm (precise) or 165 cm (rounded). 5’4″ = 162.56 cm. Inch Calculator notes that 5’5″ is “slightly taller than 165 cm”—a difference of just 0.1 cm or 1 millimeter.
Common confusions
Some charts round to the nearest centimeter, which is why you may see 5’5″ listed as 165 cm instead of 165.1 cm. The Albireo body converter table uses the rounded value. This 1 mm difference has no practical impact for most uses, but it explains why some sources appear to disagree.
Medical and health forms often ask for height in centimeters, and some round to the nearest whole number. For medical accuracy, note that 165.1 cm is the precise value—165 cm is a rounded approximation used for convenience.
Is 170 cm 5’5″ or 5’7″?
One hundred seventy centimeters equals 5’7″ (170.18 cm precisely), not 5’5″. The gap between the two heights is significant: 170.18 cm minus 165.1 cm = 5.08 cm, or just over 2 inches. If a form lists your height as 170 cm and you think you might be 5’5″, you are likely closer to 5’7″.
Breakdown of 170 cm
5’7″ = 170.18 cm according to Inch Calculator. The nearest imperial equivalent to 170 cm is 5’7″, not 5’5″. Converting 170 cm back: 170 ÷ 2.54 = 66.93 inches, which is 5 feet and 6.93 inches—rounds to 5’7″.
Height chart reference
A reliable height chart helps you spot the difference between these close-but-distinct values. SplashLearn lists 5’5″ at 165.1 cm and 5’7″ at 170.18 cm, confirming that 170 cm rounds up to 5’7″.

Understanding where 5’5″ sits relative to nearby heights helps put the conversion in context. A few inches above or below changes the centimeter value by roughly 5-8 cm.
5 feet 4 inches
5’4″ equals 162.56 cm. The Calculator Site uses the formula 64 in × 2.54 cm/in to confirm this value.
5 feet 6 inches
5’6″ equals 167.64 cm. Inch Calculator lists this as the next height increment after 5’5″.
Visual ruler guide
The NHS height chart offers a printable visual reference. UHSussex NHS (published March 2023) displays heights from 4’10” to 6’6″ with both imperial and metric values. Printing this chart gives you a physical ruler reference for quick conversions.
The pattern shows that each additional inch adds exactly 2.54 cm, making neighboring heights predictable once you know the base conversion.
Anyone filling out international forms, applying for jobs requiring height in metric units, or comparing themselves to a global height chart can rely on 165.1 cm as the definitive answer.
| Height (imperial) | Height (cm) | Height (meters) |
