The mass of a textbook is 1.25 kg about how many pounds is this
The correct answer and explanation is:
To convert the mass of the textbook from kilograms to pounds, the conversion factor from kilograms to pounds is used. 1 kilogram is approximately equal to 2.20462 pounds. Therefore, to find the weight in pounds, multiply the mass in kilograms by this conversion factor.
For the textbook with a mass of 1.25 kg, the calculation is:
1.25 kg × 2.20462 = 2.7558 pounds
Thus, the textbook has a mass of about 2.76 pounds.
Explanation:
When converting mass or weight between metric and imperial units, a precise conversion factor is necessary to ensure accuracy. The metric system is used worldwide and the standard unit of mass is the kilogram. The imperial system, which is still used in countries like the United States, uses pounds as the unit of weight. In the metric system, the kilogram is defined as the base unit of mass.
The pound, on the other hand, is a unit of weight in the imperial system, which historically was based on the mass of a certain number of grains. However, with modern definitions, weight in pounds can be derived from the mass in kilograms by multiplying by a constant factor.
It’s also important to note that the mass and weight are often confused, but weight is a force that depends on the gravitational pull, which varies based on location. In this case, we are using the mass of the textbook in kilograms, and converting to pounds based on the standard mass conversion factor.
Knowing the mass of objects and how to convert them is useful for many practical purposes, especially in countries where one system of measurement is preferred over the other. This method can be used for any mass measurement that needs to be converted between kilograms and pounds.
