1 Pixel in Excel: How Many Cm is That?
When working with images in Microsoft Excel, you may have wondered how to measure the size of an object or an image in centimeters (cm). Since Excel uses pixels as its unit of measurement, it's essential to know how to convert pixels to cm. In this article, we'll explore how to do just that.
What is a Pixel?
A pixel (short for "picture element") is the smallest unit of a digital image or graphic. It's a tiny square that represents a single color and brightness value. In the context of computer graphics, pixels are used to create images, icons, and graphics on digital devices.
How Many Cm is 1 Pixel?
The answer to this question is not straightforward, as it depends on the resolution and dimensions of the digital device or screen. However, we can use a general guideline to estimate the size of a pixel in cm.
Pixel Density
Pixel density is measured in pixels per inch (PPI). The higher the PPI, the smaller the pixels. Here are some common PPI values for various devices:
| Device | Pixel Density (PPI) |
|---|---|
| Old monitors | 72-96 PPI |
| Standard monitors | 96-120 PPI |
| High-resolution monitors | 140-200 PPI |
| Mobile devices | 200-400 PPI |
| Print resolution | 300-600 PPI |
Converting Pixels to Cm
To convert pixels to cm, we need to know the PPI value of the device or screen. Let's assume we're working with a standard monitor having a PPI of 96.
1 pixel = 0.026458 cm (at 96 PPI)
So, if you have an image with a width of 100 pixels, the width in cm would be:
100 pixels × 0.026458 cm/pixel ≈ 2.6458 cm
Keep in mind that this is an approximate value, as the actual size may vary depending on the device and display settings.
Conclusion
In conclusion, 1 pixel in Excel corresponds to approximately 0.026458 cm on a standard monitor with a PPI of 96. When working with images in Excel, it's essential to understand how to convert pixels to cm to ensure accurate measurements and scaling.
