I would do the below when you need to use the tmp variable:

(tmp + 80f) * 0.01f

When setting the volume you will utilize the following code:

Mathf.Log10(value) *20;

What you need is the inverse:

Mathf.Pow(10, (value/20);

You can create a Remap function:

float Remap(float value, float min1, float max1, float min2, float max2) 
{
    return min2 + (value - min1) * (max2 - min2) / (max1 - min1);
}

Implementation:

audioMixerGroup.audioMixer.GetFloat("AllVolume", out tmp);
slider.value = Remap(tmp, -80f, 0f, 0f, 1f);
