What is a Centimeter?

Definition

A centimeter (cm) is a unit of length in the metric system, equal to one-hundredth of a meter (1/100 m). It's the most practical metric unit for everyday measurements of moderate-sized objects.

Key Points

• Symbol: cm
• System: Metric (SI)
• Equals: 10 millimeters, 0.01 meters, 0.393701 inches
• Used By: Every country worldwide for scientific and medical use; everyday use in all countries except the United States

Global Standard

Centimeters are the worldwide preference for:

• Medical measurements: Height, wound sizes, body dimensions
• Clothing industry: All international sizing charts
• Product specifications: Electronics, furniture, consumer goods
• Education: School rulers, geometry, science classes
• Construction: Architectural drawings (in many countries)

Why Centimeters Work Well

• Perfect for height (150-200 cm for adults)
• No fractions needed (170 cm vs. 5'7")
• Precise enough without being too small

• Easy calculations (170 cm × 2 = 340 cm)
• Simple conversions (100 cm = 1 meter)
• Universal worldwide

What is a Foot?

Definition

A foot (ft) is a unit of length in the imperial and US customary systems. One foot equals exactly 12 inches or 30.48 centimeters.

Key Points

• Symbol: ft or ' (prime symbol)
• System: Imperial/US Customary
• Equals: 12 inches, 30.48 centimeters, 0.3048 meters
• Used By: United States primarily; Canada and UK for some applications

Historical Context

The foot originated from the human foot length. The modern international foot was standardized in 1959 as exactly 0.3048 meters (30.48 centimeters).

American Preference

Americans use feet for:

• Human height measurements
• Room dimensions and floor plans
• Construction and carpentry
• Real estate listings
• Sports measurements
• Everyday conversation

Centimeter to Feet Conversion Formula

The Standard Formula

feet = centimeters ÷ 30.48

Or equivalently:

feet = centimeters × 0.0328084

Formula Breakdown

• Step 1: Take the measurement in centimeters
• Step 2: Divide by 30.48
• Result: Measurement in feet

Why This Formula Works

• 1 inch = exactly 2.54 centimeters
• 1 foot = 12 inches
• Therefore: 1 foot = 12 × 2.54 = 30.48 centimeters

• feet = cm ÷ 30.48

Mathematical Precision

The factor 30.48 is exact:

• 30.48 cm = 1 foot (exactly, by definition)
• No approximation involved
• Infinitely precise for calculations

Converting to Feet and Inches

For height, often expressed as feet'inches:

• Step 1: Convert to feet
• 175 ÷ 30.48 = 5.741 feet
• Step 2: Separate whole feet
• 5 feet + 0.741 feet
• Step 3: Convert decimal to inches
• 0.741 × 12 = 8.89 inches
• Answer: 175 cm = 5 feet 8.89 inches (approximately 5'9")

Reverse Calculation

To convert feet back to centimeters: centimeters = feet × 30.48

How to Calculate Centimeters to Feet

Method 1: Simple Division

• Step 1: Divide by 30.48
• 180 ÷ 30.48 = 5.906

Answer: 180 cm = 5.906 feet (approximately 5'11")

Method 2: Converting to Feet and Inches

• Step 1: Divide by 30.48
• 165 ÷ 30.48 = 5.413 feet
• Step 2: Separate whole and decimal
• 5 whole feet
• 0.413 feet remaining
• Step 3: Convert decimal to inches
• 0.413 × 12 = 4.96 inches

Answer: 165 cm = 5 feet 5 inches (5'5")

Method 3: Quick Approximation

For rough estimates: Divide cm by 30 (close approximation)

• Quick: 150 ÷ 30 = 5 feet
• Actual: 150 ÷ 30.48 = 4.92 feet
• Close enough for conversation!

Method 4: Benchmark Method

Remember key conversions and interpolate:

• 30 cm ≈ 1 foot
• 152 cm = 5 feet
• 183 cm = 6 feet

• Between 152 (5 ft) and 183 (6 ft)
• Closer to 183
• Estimate: ~5'7" or 5'8"
• Actual: 5.58 feet = 5'7"
