What is Parkland Formula Calculator (Burn Fluid)?
The Parkland Formula Calculator (Burn Fluid) calculation tells you your total fluid in first 24 hours from a few simple inputs. The figure you are solving for here is the total fluid in first 24 hours.
The Parkland Formula Calculator (Burn Fluid) formula
The core formula is:
Total fluid in first 24 hours = 4 × Body weight × Burned body surface areaHere is what each input means:
- Body weight — a value measured in kg. Example: 70 kg.
- Burned body surface area — a percentage, such as an annual rate. Example: 3%.
How to calculate it step by step
- Write down the body weight (for example, 70 kg).
- Write down the burned body surface area (for example, 3%).
- Apply the formula above to get your total fluid in first 24 hours.
- Double-check the result with the Parkland Formula Calculator (Burn Fluid).
Worked examples
Example 1
| Input / Output | Value |
|---|---|
| Body weight | 70 kg |
| Burned body surface area | 3% |
| Total fluid in first 24 hours | 8,400 |
| Given in first 8 hours | 4,200 |
With body weight of 70 kg and burned body surface area of 3%, the total fluid in first 24 hours works out to 8,400.
Example 2
With body weight of 140 kg and burned body surface area of 3%, the total fluid in first 24 hours works out to 16,800.
| Result | Value |
|---|---|
| Total fluid in first 24 hours | 16,800 |
| Given in first 8 hours | 8,400 |
Example 3
With body weight of 35 kg and burned body surface area of 3%, the total fluid in first 24 hours works out to 4,200.
| Result | Value |
|---|---|
| Total fluid in first 24 hours | 4,200 |
| Given in first 8 hours | 2,100 |
Tips for an accurate result
- Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
- Round only at the very end. Rounding inputs early can shift the final answer noticeably.
- Re-run the numbers whenever an input changes, rather than estimating from an old result.
- These figures are general estimates, not medical advice — check with a qualified professional before acting on them.
