Example of Weight For Age Calculation

Let’s understand how the calculator works with an example:

Scenario:

• Age: 25 years
• Actual Weight: 65 kg
• Standard Weight: 70 kg

Step 1: Apply Formula

Weight Ratio = (65 ÷ 70) × 100
Weight Ratio = 92.8%

Step 2: Result Interpretation

• 92.8% falls in the Normal range (80% - 120%)
• Status: Normal Weight

Another Example:

• Age: 30 years
• Weight: 50 kg
• Standard Weight: 70 kg

Weight Ratio = 71.4%
Status = Underweight

This shows how easily you can understand your weight condition using this tool.

Understanding Weight Status Results

The calculator categorizes results into three main health conditions:

Underweight (< 80%)

If your weight ratio is below 80%, it means you may be underweight. This can indicate:

Normal Weight (80% – 120%)

This range is considered healthy. It means your weight is appropriate for your age and body type.

• Poor diet
