Using the approximate conversion factors in Table 1.5, convert the following SI units to English units without using your calculator. (b) 25 m/s

Verified step by step guidance

1. Identify the conversion factor from meters per second (m/s) to feet per second (ft/s) from Table 1.5. Typically, the conversion factor is approximately 3.281 feet per meter.
2. Set up the conversion equation using the given speed and the conversion factor. Multiply the speed in meters per second by the conversion factor to convert it to feet per second.
3. Write the equation: Speed in ft/s = 25 m/s * 3.281 ft/m.
4. Perform the multiplication to convert 25 meters per second to feet per second.
5. Express the result in feet per second (ft/s) to complete the conversion.

Key Concepts

Unit Conversion

Unit conversion is the process of converting a quantity expressed in one set of units to another set of units. This involves using conversion factors, which are ratios that express how many of one unit are equivalent to another. For example, to convert meters to feet, one might use the conversion factor of 1 meter = 3.28084 feet.

SI Units

The International System of Units (SI) is a standardized system of measurement used globally in science and engineering. It includes base units such as meters for length, kilograms for mass, and seconds for time. Understanding SI units is crucial for accurately interpreting measurements and performing conversions to other unit systems, such as English units.

English Units

English units, also known as imperial units, are a system of measurement commonly used in the United States and a few other countries. This system includes units such as feet, pounds, and seconds. When converting from SI to English units, it is important to know the appropriate conversion factors to ensure accuracy in the results.
