Certainly! Let’s break down the task step by step: --- ## **Step-by-Step Solution** ### **Step 1: Understand the Problem** You need to convert a measurement in pixels (from a video) to a physical length (in inches or centimeters). The video has a ruler with an inch scale, and you are given the conversion: **1 inch = 2.54 cm** --- ### **Step 2: Identify the Pixel-to-Inch Scale** 1. **Pause the video** at a point where the ruler is clearly visible. 2. **Measure the number of pixels** that correspond to a known length on the ruler (e.g., 1 inch or 2 inches). - Use a screen ruler tool or image analysis software to do this. - Let’s say, for example, 1 inch on the ruler = **150 pixels**. --- ### **Step 3: Set Up the Pixel-to-Physical Scale** - **Scale:** \[ \text{Physical length} = \left(\frac{\text{Measured length in pixels}}{\text{Pixels per inch}}\right) \text{ inches} \] --- ### **Step 4: Convert to Centimeters (if needed)** - Multiply the length in inches by **2.54** to get centimeters. --- ### **Step 5: Example Calculation** Suppose you measure **1 inch = 150 pixels**, and an object in the video is **300 pixels** long. #### **A. Convert Pixels to Inches** \[ \text{Length in inches} = \frac{300 \text{ pixels}}{150 \text{ pixels/inch}} = 2 \text{ inches} \] #### **B. Convert Inches to Centimeters** \[ \text{Length in cm} = 2 \text{ inches} \times 2.54 = 5.08 \text{ cm} \] --- ## **Final Answer (General Formula)** If \( P \) is the length in pixels, and \( S \) is the scale (pixels per inch): \[ \text{Length in inches} = \frac{P}{S} \] \[ \text{Length in cm} = \frac{P}{S} \times 2.54 \] --- ## **Summary** 1. Measure how many pixels correspond to 1 inch on the video ruler. 2. Use the ratio to convert any pixel measurement to inches (or centimeters). 3. **1 inch = 2.54 cm** for further conversion. --- If you provide the actual pixel measurements from your video, I can calculate a specific answer!
