High-School Specific GPA Calculations

<p>This is probably a ridiculously stupid question, but my high school records on a 4.0 scale
4.0=A+ (97-100)
3.8= A (93-96)
3.7=A-(90-92)</p>

<p>As i understand it, colleges convert differently, with an A being a 4.0.
When they look at my GPA, will they consider it on a scale based on my high school or their own determination?
Rather, would a 4.0 at my school be seen by admissions as an A+ (97) or an A (93)?</p>

<p>I'm assuming they base their scale on each high school's individual scale, but I'm not sure. Could anyone enlighten me?</p>
