Learning Inches and Centimeters

We learn inches and centimeters first before we go ahead and convert

Inch (in): unit of measurement, used in America and others.
Centimeter (cm): Metric unit of measurement, utilized primarily in science and internationally.

Conversion formula

1 inch = 2.54 centimeters
It’s actually just a case of whatever the measurement is in inches and same with cm and it’s as easy as just multiply it by 2.54.

Why Convert Inches to CM

There actually are quite a number of real-life scenarios where inches to cm conversion just can’t be helped:

 

Use Case Why It Matters
Online Shopping Sizes of products can be quoted in inches; overseas customers will need cm.
Carpentry and Interior Design Tiles, fittings, shelves, etc., should be measured accurately.
Science and Engineering Scientifically accurate wherever in the globe metric system is used.
Education Homework drawings are metric standard.
Medical Profession Patient’s height, medical equipment specifications of medicine almost always have to be quoted in cm.

Step-by-Step: Inches to CM

Let’s go through a practical guide:

Step 1: Know the Formula
Since we have learnt:
cm = inch × 2.54
If it is 5 inches then you do:
5 × 2.54 = 12.7 cm

Step 2: Write Down the Measurement in Inches
For instance, we are measuring a laptop screen and it is 13.3 inches.

Step 3: Multiply the Inch Measurement with 2.54
13.3 × 2.54 = 33.782 cm
Your 13.3-inch monitor is 33.782 centimeters diagonal.

Step 4: Round Off (if necessary)
If to do to buy hand with handy guide or to buy
33.782 cm ≈ 33.8 cm
But for medical process, engineering process or designing process i.e. require more decimals to be precise.

Step 5: Double Check using Calculator

A calculator or an online inches to cm converter can be used. Computer softwares most will have the formula and the answers.

Area Conversion: Square Inches to Square Centimeters

Length is but one of the ones you’ll be converting over—area enters the picture when you are constructing buildings, floor plans, and dressing up.

You’ll have to square the conversion factor if you want to convert square inches to square centimeters

1 square inch = 6.4516 square centimeters

Area Conversion Formula

Area (cm²) = Area (in²) × 6.4516

Example
40 in² is room’s carpet area. You do:
40 × 6.4516 = 258.064 cm²

Area Conversion Calculator (Handheld Calculator)

Quickly convert using handheld calculator

Step 1: Insert Length and Width in Inches
e.g., Length = 12 in, Width = 10 in

N2: Calculate Area in Square Inches
12 in × 10 in = 120 in²

N3: Convert Square Inches to Square Centimeters
120 × 6.4516 = 774.192 cm²

Inches to CM Calculator – When and Why Use It

Easy enough to do by yourself, but benefits of using an inches to cm calculator:
