When working with speeds or rates of movement, it’s common to encounter different units of measurement. Inches per minute (in/min) and centimeters per second (cm/s) are two such units that might be used in various fields, such as physics, engineering, or when dealing with motion. Inches per minute is typically used in countries that follow the imperial system, while centimeters per second is a metric unit.

This article explains how to convert between inches per minute and centimeters per second, making it easy to switch between these units.

Why Convert Inches per Minute to Centimeters per Second?

The need for conversion often arises when working in different systems of measurement. For example, if you’re using an imperial system in one part of your work and then collaborating with teams using the metric system, converting these units is essential. Converting inches per minute to centimeters per second ensures consistency and accuracy across measurements, especially in technical and scientific fields.

Conversion Formula: Inches per Minute to Centimeters per Second

To convert inches per minute (in/min) to centimeters per second (cm/s), you need to multiply the number of inches per minute by 0.423333. This conversion factor arises from the fact that 1 inch = 2.54 centimeters, and 1 minute = 60 seconds.

Formula: 1 in/min = 0.423333 cm/s

For example:

• 1 in/min = 0.423333 cm/s
• 10 in/min = 4.23333 cm/s
• 50 in/min = 21.16665 cm/s

Step-by-Step Guide: Converting Inches per Minute to Centimeters per Second

1. Identify the number of inches per minute (in/min) you want to convert.
2. Multiply that number by the conversion factor 0.423333.
3. The result will be in centimeters per second (cm/s).

Example Calculation

Let’s say you’re measuring a velocity of 20 inches per minute and you want to convert this to centimeters per second. Here’s how to do it:

20 in/min × 0.423333 cm/s = 8.46666 cm/s

So, 20 inches per minute equals 8.47 centimeters per second.
