.**Enter Fluid Density:**Input the density in kg/m³ or lb/ft³. For example,`1.225 kg/m³`

.**Calculate Dynamic Pressure:**Click “Calculate” to get the result.

**What is Velocity to Pressure?**

Velocity to Pressure conversion is used in fluid dynamics to find the pressure exerted by a moving fluid. It is crucial for understanding fluid behavior in various applications.

### Formula

The formula to calculate dynamic pressure is:

`$P=\frac{{V}^{2}\times d}{2}$`

**Variables**

Variable | Description |
---|---|

P | Dynamic Pressure (Pa) |

V | Velocity (m/s) |

d | Fluid Density (kg/m³) |

### How To Convert Velocity To Pressure

**Example 1**

**Input:**

- Velocity = 15 m/s,
- Fluid Density = 1.225 kg/m³

**Calculation:**

$P=\frac{1{5}^{2}\times 1.225}{2}$

`1. Use the formula:`

$1{5}^{2}=225$

`2. Calculate`

`3. Multiply 225 by 1.225 = 275.625`

`4. Divide by 2 = 137.8125`

`Result: P ≈ 137.81 Pa`

#### Example 2

**Input:**

- Velocity = 20 m/s,
- Fluid Density = 1.5 kg/m³

**Calculation:**

$P=\frac{2{0}^{2}\times 1.5}{2}$

`1. Use the formula:`

$2{0}^{2}=400$

`2. Calculate`

`3. Multiply 400 by 1.5 = 600`

`4. Divide by 2 = 300`

`Result: P = 300 Pa`
