Whether you’re trying to pack for international travel, adjusting a recipe, or tracking your fitness goals, at some point you’ll probably need to convert kilograms into pounds, or vice versa.
Here, we’re going to focus on converting 7.3 kg to lbs. We’ll also touch on ounces, since they’re part of the imperial system too.
We’ll walk you through the conversion process, talk about getting the right level of precision, and cover other related concepts.
Converting 7.3 kg to Pounds: A Step-by-Step Guide
So, you need to know what 7.3 kilograms is in pounds? No problem. Here’s how to do the conversion:
The Basic Conversion Formula
The quick-and-dirty conversion factor is that 1 kilogram is about 2.204623 pounds. To find out how many pounds are in 7.3 kilograms, you’d multiply 7.3 by 2.204623. So:
7.3 kg 2.204623 lbs/kg = 16.0937479 lbs
Higher Precision Conversion
For some applications, you might need a more precise conversion. The higher precision formula is kilograms multiplied by 2.20462262185. You might need this level of precision for scientific work or in manufacturing, where tiny differences can be critical.
When we apply that to 7.3 kg, we get:
7.3 kg 2.20462262185 = 16.093745149505 lbs
Rounding Considerations
Depending on what you’re using the measurement for, you may want to round the result. If you’re just trying to get a sense of your body weight, rounding to the nearest pound might be fine. If you’re shipping something, rounding to the nearest tenth or hundredth might be necessary.
Here are some examples of rounding:
- Basic formula (16.0937479 lbs): Rounded to the nearest whole number: 16 lbs; to the nearest tenth: 16.1 lbs; to the nearest hundredth: 16.09 lbs.
- Higher precision formula (16.093745149505 lbs): Rounded to the nearest whole number: 16 lbs; to the nearest tenth: 16.1 lbs; to the nearest hundredth: 16.09 lbs.
Converting the decimal portion to ounces
Sometimes, you’ll see weights given in both pounds and ounces. This is because pounds can be further broken down into smaller units called ounces.
Remember that 1 pound equals 16 ounces.
To convert the decimal portion of our pound result (16.0937 lbs) into ounces, we’re going to take the decimal part (.0937) and multiply it by 16:
.0937 x 16 = 1.4992 ounces
So, 7.3 kilograms is equal to 16 pounds and 1.4992 ounces.
But what if you want to express that .4992 ounces as a fraction?
To do that, you’ll need to simplify the ounce value to a common fraction. In this case, .4992 is very close to .5, which we know is one-half, or 1/2.
So, we can say that 7.3 kg = 16 pounds and about 1 1/2 ounces.
Understanding Kilograms and Pounds: Definitions and Context
To really understand the conversion from kilograms to pounds, it helps to understand what each of these units measures.
Defining the Kilogram
The kilogram is the base unit of mass in the metric system. It’s equal to 1,000 grams.
The kilogram used to be defined as the mass of a specific platinum-iridium cylinder, but the definition has evolved over time to be based on fundamental physical constants.
Defining the Pound
The pound is a unit of mass in both the US customary and imperial systems of measurement. There are 16 ounces in a pound.
One pound is equal to 0.45359237 kilograms.
Different Types of Ounces
It’s worth knowing that there are different kinds of ounces. There are avoirdupois ounces, troy ounces, and fluid ounces. But when we’re talking about weight, we’re usually talking about the avoirdupois ounce.
