How to Calibrate with a Rp1000 Coin
- Open the screen ruler on your device and select Rp1000 Coin from the calibration panel.
- Place your rp1000 coin flat on the screen, aligning it with the on-screen outline.
- Adjust the calibration slider until the outline matches your rp1000 coin exactly.
- The calibration is saved automatically. You can now measure any object with the ruler and get accurate readings in centimeters, millimeters, and inches.
Why Use a Rp1000 Coin for Calibration?
Calibration is essential because every screen has a different pixel density (PPI). A pixel on a 6-inch phone screen is physically much smaller than a pixel on a 27-inch desktop monitor. By placing a known-size object on the screen, the ruler can calculate the exact physical size of each pixel and convert measurements accurately.
Coins like the Rp1000 Coin are particularly useful because they are standardized, widely available, and easy to position on a screen. Their circular shape makes alignment straightforward.
