Convert from length units to desired length units

• 

Length 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 Length Conversion block computes the conversion factor from specified input length units to specified output length units and applies the conversion factor to the input signal.

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

Ports

Input

Port_1 — Length

scalar | array

Length, specified as a scalar or array, in initial length units.

Dependencies

The input port label depends on the Initial unit setting.

Data Types: double

Output

Port_1 — Length

scalar | array

Length, returned as a scalar or array, in final length units.

Dependencies

The output port label depends on the Final unit setting.

Data Types: double

Parameters

Initial unit — Input units

ft (default) | m | km | in | mi | naut mi

Input units, specified as:

m	Meters
ft	Feet
km	Kilometers
in	Inches
mi	Miles
naut mi	Nautical miles

Dependencies

The input port label depends on the Initial unit setting.

Programmatic Use

Block Parameter: IU

Type: character vector

Values: 'm' | 'ft' | 'km' | 'in' | 'mi' | 'naut mi'

Default: 'ft'

Final unit — Input units

m (default) | ft | km | in | mi | naut mi

Output units, specified as:

m	Meters
ft	Feet
km	Kilometers
in	Inches
mi	Miles
naut mi	Nautical miles

Dependencies

The output port label depends on the Final unit setting.

Programmatic Use

Block Parameter: OU

Type: character vector

Values: 'm' | 'ft' | 'km' | 'in' | 'mi' | 'naut mi'

Default: 'm'

Programmatic Use: Add Block

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

"aerolibconvert2/Length Conversion"

Example: add_block("aerolibconvert2/Length Conversion","myModel/myBlock",MakeNameUnique="on")
