![### Unit Conversion: Kilograms to Pounds
**Question 36 of 40**
**Prompt:**
A bench press bar has a mass of **20.4 kg**. How many **lb** (pounds) is this?
**Components of the Interface:**
1. **Starting Amount Section**:
- A space to input the starting amount which in this case is 20.4 kg.
2. **Multiplication Factor Area**:
- This section is used to input the conversion factor to convert kg to pounds.
3. **Additional Options**:
- Add Factors: Allows for additional conversion factors or operands in the equation.
- Answer: The solution box to show the final answer.
- Reset: A button to reset all fields and start again.
**Provided Data:**
- Conversion factors and constants:
- 20.4 (presumably the number of kilograms)
- 2.205 (likely the factor to convert kg to lb)
- 1 (presumably to signify unity in other conversions like g to kg)
- 45.0
- 1000
- 453.6
- 0.001
**Objective:**
To convert the given mass from kilograms to pounds.
### Step-by-Step Conversion:
1. **Identify the Conversion Factor**:
- To convert kilograms to pounds, use the conversion factor **1 kg = 2.205 lb**.
2. **Calculate the Mass in Pounds**:
- Multiply the given mass by the conversion factor:
\[
\text{Mass in pounds} = 20.4 \, \text{kg} \times 2.205 \, \frac{\text{lb}}{\text{kg}}
\]
3. **Perform the Calculation**:
- \[
20.4 \times 2.205 = 44.982 \, \text{lb}
\]
4. **Result**:
- The mass of the bench press bar in pounds is approximately **44.982 lb**.
### Visual Interface:
- **Input Fields**:
- Starting Amount: "20.4"
- Conversion Factor: "2.205"
- **Answer Displays**:
- The calculated answer should be shown in the answer box after performing the multiplication.
**Note**: Ensure accurate inputs of values in the corresponding fields to obtain](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc25e6886-23a3-4870-9519-3bb0f78f33bc%2F1ae39cb8-e206-4ebe-ba72-bf87226ed6bc%2Fzlxi43g_processed.jpeg&w=3840&q=75)
