Calculating your wind pressure is straightforward once you know the Wind Pressure formula and what each input means. This guide explains the method in plain language, walks through a manual calculation, and gives worked examples you can follow — then you can do it instantly with the Wind Pressure Calculator.
What is Wind Pressure?
The Wind Pressure calculation tells you your wind pressure from a few simple inputs. The figure you are solving for here is the wind pressure.
The Wind Pressure formula
The core formula is:
Wind pressure = 0.613 × Wind speed ^ 2Here is what each input means:
- Wind speed — a value measured in m/s. Example: 20 m/s.
How to calculate it step by step
- Write down the wind speed (for example, 20 m/s).
- Apply the formula above to get your wind pressure.
- Double-check the result with the Wind Pressure Calculator.
Worked examples
Example 1
| Input / Output | Value |
|---|---|
| Wind speed | 20 m/s |
| Wind pressure | 245.20 |
With wind speed of 20 m/s, the wind pressure works out to 245.20.
Example 2
With wind speed of 40 m/s, the wind pressure works out to 980.80.
| Result | Value |
|---|---|
| Wind pressure | 980.80 |
Example 3
With wind speed of 10 m/s, the wind pressure works out to 61.30.
| Result | Value |
|---|---|
| Wind pressure | 61.30 |
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.
