R2026b

Convert from pressure units to desired pressure units

• 

Pressure Conversion block

To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.

Libraries:
Aerospace Blockset / Utilities / Unit Conversions

Description

The Pressure Conversion block computes the conversion factor from specified input pressure units to specified output pressure units and applies the conversion factor to the input signal.

The Pressure Conversion block port labels change based on the input and output units selected from the Initial unit and the Final unit lists.

Examples

Convert Pressure

Convert pressure from psi to Pa.

Ports

Input

Port_1 — Pressure

scalar | array

Pressure, specified as a scalar or array, in initial pressure units.

Dependencies

The input port label depends on the Initial unit setting.

Data Types: double

Output

Port_1 — Pressure

scalar | array

Pressure, returned as a scalar or array, in final pressure units.

Dependencies

The output port label depends on the Final unit setting.

Data Types: double

Parameters

Initial unit — Input units

psi (default) | Pa | psf | atm

Input units, specified as:

psi	Pound mass per square inch
Pa	Pascals
psf	Pound mass per square foot
atm	Atmospheres

Dependencies

The input port label depends on the Initial unit setting.

Programmatic Use

Block Parameter: IU

Type: character vector

Values: 'psi' | 'Pa' | 'psf' | 'atm'

Default: 'psi'

Final unit — Output units

Pa (default) | psi | psf | atm

Output units, specified as:

psi	Pound mass per square inch
Pa	Pascals
psf	Pound mass per square foot
atm	Atmospheres

Dependencies

The output port label depends on the Final unit setting.

Programmatic Use

Block Parameter: OU

Type: character vector

Values: 'psi' | 'Pa' | 'psf' | 'atm'

Default: 'Pa'

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.
