===== Description =====
Converts acceleration (mapunits^2 per tic) to ''sv_gravity'' units.

<note tip>800 sv_gravity units = 1 mapunit^2 per tic</note>

<note important>This function returns a fixed-point number, not an integer.</note>

===== Examples =====
<code>
accel2grav(1.0) -> 800.0;
accel2grav(0) -> 0.0;
accel2grav(2.0) -> 1600.0;
