What is the Difference Between Scale and Ruler?
🆚 Go to Comparative Table 🆚The main difference between a scale and a ruler lies in their purpose and usage:
- Scale: A scale is a device used for measuring linear distance and creating proportional linear measurements. It is often used in scientific and engineering terminology. Scales are typically limited in use and have a fixed ratio for measurements. Some common types of scales include engineer's scale, linear encoder, vernier scale, and architect's scale.
- Ruler: A ruler, on the other hand, is an instrument used for drawing straight lines and measuring lengths. It is sometimes referred to as a straightedge or line gauge. Rulers are more versatile than scales and can be used for various purposes, such as drawing accurate graphs in algebra and other math topics. Rulers can be found in different shapes and sizes, including circular rulers for measuring distances around curves.
In summary, a scale is a device for measuring and transferring lengths at a fixed ratio, while a ruler is an instrument used for drawing straight lines and measuring lengths. Although both are often referred to as a ruler, their purposes and uses are different.
Comparative Table: Scale vs Ruler
The main difference between a scale and a ruler lies in their purpose and the measurements they are used for. Here is a comparison table highlighting the differences:
| Feature | Ruler | Scale |
|---|---|---|
| Purpose | Primarily used for linear measurements. | Primarily used for measuring weight or mass. |
| Usage | Used for measuring distances on a flat, straight-edged tool. | Used for weighing objects on a measuring instrument with graduated linear or circular markings. |
| Objects Measured | Commonly used for measuring small distances and is found in offices, schools, and homes. | Commonly used for measuring larger objects and is found in laboratories, factories, and other industrial settings. |
| Application in Cooking | Can be used to measure ingredients by length or volume. | Can be used to measure ingredients by weight. |
| Examples of Types | Includes flat or triangular scale rulers with multiple graduated scales. | Includes engineer's scale, linear encoder, vernier scale, and architect's scale. |
In summary, a ruler is typically used for linear measurements, while a scale is used for measuring weight or mass. Scales and rulers serve different purposes and are designed for different applications.
