Cara Pertukaran Piksel → cm Berfungsi

Anda memerlukan ketumpatan piksel (PPI). Satu inci = 2.54 cm. Formula:

Pixels to CM
cm = pixels ÷ PPI × 2.54
CM to Pixels
pixels = cm ÷ 2.54 × PPI
Live Example at 96 PPI:
100 px
2.65 cm

Contoh: pada 96 PPI, 100 px ≈ 2.65 cm. Pada 300 PPI, 100 px ≈ 0.85 cm.

PPI vs DPI

PPI untuk resolusi digital. DPI untuk pencetak. Gunakan PPI untuk saiz fizikal.

Adakah 1000 px cukup besar?

Untuk web sudah memadai. Untuk cetakan, anda perlukan dimensi lebih tinggi.

What is a Pixel (PX)?

A pixel (px) is the smallest addressable element of a raster image displayed on a screen. The word "pixel" is a combination of "picture" and "element." Each pixel represents a single point of color, and millions of pixels together form the images you see on monitors, phones, and tablets.

Pixels have no fixed physical size — their real-world dimensions depend on the display's pixel density (PPI). A pixel on a 27-inch 1080p monitor is physically larger than a pixel on a 6-inch smartphone with the same resolution.

Key fact: A standard web display uses 96 PPI, meaning each pixel is approximately 0.0265 cm (0.265 mm) wide.

What is a Centimeter (CM)?

A centimeter (cm) is a metric unit of length equal to one hundredth of a meter. It is widely used around the world for everyday measurements — from paper sizes (A4 is 21 × 29.7 cm) to screen dimensions and print layouts.

Unlike pixels, centimeters represent a fixed physical size. When designers and print professionals need to specify how large an image will appear on paper or in the physical world, they use centimeters (or inches). Converting between pixels and centimeters requires knowing the resolution (PPI) of the output device.

Key fact: 1 inch = 2.54 cm. This constant is the bridge between pixels (digital) and centimeters (physical).

What is DPI (Dots Per Inch)?

DPI (Dots Per Inch) measures how many ink dots a printer places within one linear inch. Higher DPI means finer detail and smoother prints. Common print DPI values include 150 (draft), 300 (standard quality), and 600+ (high-quality or photo prints).

While DPI is often used interchangeably with PPI, they are technically different. PPI (Pixels Per Inch) refers to digital screen resolution, while DPI refers to printer output. For pixel-to-cm conversion, PPI is the correct value to use.

PPI (Screens)

72, 96, 150, 200, 300 PPI

DPI (Printers)

150, 300, 600, 1200 DPI

Pixel to CM Formula

The conversion between pixels and centimeters uses a straightforward mathematical formula based on the pixel density (PPI):

Pixels → CM
cm = (pixels / PPI) × 2.54
CM → Pixels
pixels = (cm / 2.54) × PPI

Step-by-step example: Convert 500 pixels to cm at 96 PPI:

  1. Divide pixels by PPI: 500 ÷ 96 = 5.208 inches
  2. Multiply by 2.54: 5.208 × 2.54 = 13.23 cm

How Pixels to CM Conversion Table Works

A pixels to cm conversion table provides quick, pre-calculated results so you don't need to do the math yourself. Each row shows a pixel value and its equivalent in centimeters at a specific PPI. Below is a multi-PPI comparison table for the most commonly used pixel values:

50 px1.76 cm1.32 cm0.85 cm0.42 cm

How to read this table: Find your pixel value in the left column, then look across to the PPI column that matches your display or print setting. The intersection gives you the physical size in centimeters.

Pixels to CM Dimensions

Common screen resolutions and their physical dimensions at 96 PPI (standard web display):

Resolution (px) Width (cm) Height (cm)
1200 × 160031.7542.33
1024 × 153627.0940.64
1080 × 135028.5835.72
3024 × 403280.01106.68
1920 × 108050.8028.58

1600 × 40042.3310.58

2550 × 330067.4787.31
3840 × 2160101.6057.15

Note: These dimensions change with PPI. At 300 PPI (print), the same 1920×1080 image would only be 16.26 × 9.14 cm.

Pixels to CM Ratio

The pixel-to-centimeter ratio varies depending on the PPI setting. Here's a quick reference for the most common PPI values:

72 PPI
1 px = 0.0353 cm
1 cm ≈ 28.35 px
96 PPI
1 px = 0.0265 cm
1 cm ≈ 37.80 px
150 PPI
1 px = 0.0169 cm
1 cm ≈ 59.06 px
200 PPI
1 px = 0.0127 cm
1 cm ≈ 78.74 px
300 PPI
1 px = 0.0085 cm
1 cm ≈ 118.11 px
600 PPI
1 px = 0.0042 cm
1 cm ≈ 236.22 px

The higher the PPI, the more pixels fit into each centimeter — resulting in sharper, more detailed images.

Soalan Lazim

Berapakah bilangan piksel dalam 1 cm?
Ia bergantung pada PPI. Formula: piksel = cm ÷ 2.54 × PPI. Contoh: pada 96 PPI, 1 cm ≈ 0.03 px (≈ 37.8 px).
Apakah 4.5 cm * 3.5 cm dalam piksel?
Darabkan setiap dimensi dengan PPI/2.54. Pada 96 PPI: 170 × 132 px (dibundarkan kepada integer terdekat).
Berapakah saiz resolusi 1920x1080 dalam cm?
Pada 96 PPI: lebar ≈ 50.8 cm, tinggi ≈ 28.58 cm.
Bolehkah saya menukar piksel ke cm?
Ya. Anda mesti tahu PPI (piksel per inci). Gunakan penukar di atas atau formula cm = piksel ÷ PPI × 2.54.
Adakah 1000 piksel cukup besar untuk foto?
Bergantung pada penggunaan. Untuk skrin biasanya memadai. Untuk cetakan berkualiti tinggi, sasarkan dimensi piksel lebih besar dan PPI lebih tinggi (cth., 300 PPI).
Apakah perbezaan antara DPI dan PPI?
PPI ialah piksel digital per inci. DPI ialah titik pencetak per inci. Pencetak mungkin menggunakan banyak titik untuk menghasilkan satu piksel.
Apakah maksud px dalam saiz imej?
px bermaksud piksel — elemen asas imej digital. Lebar dan tinggi dalam px ialah kiraan piksel secara mendatar dan menegak.
Adakah penukaran berubah berdasarkan resolusi skrin saya?
Ya. Saiz fizikal bergantung pada PPI peranti. Untuk ukuran fizikal yang tepat, gunakan PPI sebenar paparan atau PPI pencetak yang dimaksudkan.
Berapa piksel dalam satu cm?
Bilangan piksel per sentimeter bergantung pada PPI. Formula: 1 cm = PPI ÷ 2.54 piksel. Pada 96 PPI, 1 cm ≈ 37.80 px. Pada 72 PPI, 1 cm ≈ 28.35 px. Pada 300 PPI, 1 cm ≈ 118.11 px.
Berapa piksel yang sama dengan 1 cm?
Pada resolusi web standard 96 PPI, 1 cm bersamaan kira-kira 37.80 piksel. Pada 72 PPI ia kira-kira 28.35 px, pada 150 PPI kira-kira 59.06 px, dan pada 300 PPI kira-kira 118.11 px. Formula: piksel = 1 ÷ 2.54 × PPI.
