The Correct Answer and Explanation is:
Of course. Here is the answer and an explanation for converting 148 pounds to kilograms.
148 pounds (lbs) is equal to approximately 67.13 kilograms (kg).
To understand how to perform this conversion, it is essential to know the relationship between pounds and kilograms. The pound (lb) is a unit of mass primarily used in the imperial and United States customary systems of measurement. The kilogram (kg) is the base unit of mass in the International System of Units (SI), which is used by most of the world for scientific and everyday measurements.
There are two primary methods to convert pounds to kilograms:
1. Division Method
This is the most common method. The internationally agreed upon conversion factor states that 1 kilogram is equivalent to approximately 2.20462 pounds. Therefore, to find out how many kilograms are in a certain number of pounds, you divide the pound value by this factor.
The formula is:
Kilograms = Pounds / 2.20462
Applying this to your question:
148 lbs / 2.20462 = 67.1316 kg
For most practical purposes, rounding to two decimal places is sufficient, which gives us 67.13 kg.
2. Multiplication Method
This method involves knowing the kilogram equivalent of a single pound. One pound is equal to approximately 0.453592 kilograms. To convert, you can multiply the number of pounds by this value.
The formula is:
Kilograms = Pounds × 0.453592
Applying this to your question:
148 lbs × 0.453592 = 67.1316 kg
Again, rounding this gives the same result of 67.13 kg.
A Quick Estimation Trick
For a quick mental calculation when you do not have a calculator, you can use a simpler, less precise approximation. A common trick is to divide the number of pounds by 2 and then subtract 10% of that result.
- First, 148 / 2 = 74.
- Then, 10% of 74 is 7.4.
- Finally, 74 – 7.4 = 66.6 kg.
This estimate of 66.6 kg is very close to the precise answer and is useful for quickly gauging the weight in kilograms.
