# Position units

Position conversions can be calculated in two phases:

- Computing the feedback resolution.
- Applying the conversion factors of the desired units.

## Computing feedback resolution

### Position

The position resolution depends directly on the feedback used and is based on EMCL units (c). EMCL supports as position feedbacks:

- Digital encoder
- Digital halls
- Analog halls
- Analog input
- SinCos
- PWM encoder
- Resolver

#### Digital Encoder

The resolution of the tachometer is computed as follow:

#### Digital halls

#### Analog halls

Analog Halls constant value is always 4096.

#### Analog input

Analog Input constant value is always 4096.

#### SinCos

SinCos constant value is always 1024.

#### PWM encoder

PWM encoder constant is always 65535

#### Resolver

Resolver constant is always 65535.

#### SSI

## Applying the conversion factors of the desired units

A direct conversion factor can be applied to obtain the desired units after the computation of the resolution. The next sections shows the conversions of the most typical units.
