JAVA if Statement works and doesn't work at the same time

The problem is my if Statement. The second if works as designed, it prints out what I asked, but the first one does not even though they are formatted the same way, and defaults to the else statement. I just want to know what I did wrong.

The First if

     if(systemChoice.equals("M")){
        weight = height * height * 25;
        outputLabel.setText(name + ", your ideal weight is " + weight + " kgs.");

The Second if

    if(systemChoice.equals("I")){
        weight = height * height * 25 / 703;
        outputLabel.setText(name + " , your ideal weight is " + weight + " lbs");
    }

And here is the whole program in context if necessary

     String name, systemChoice;
    double height, weight;

    name = nameInput.getText();
    systemChoice = systemInput.getText();
    height = Double.parseDouble(heightInput.getText());

    /*Calculates your ideal weight 
    *based on a bmi formula in 
    *your preferred system of measurement
    *Imperial or Metric
    */
    if(systemChoice.equals("M")){
        weight = height * height * 25;
        outputLabel.setText(name + ", your ideal weight is " + weight + " kgs.");
    }
    if(systemChoice.equals("I")){
        weight = height * height * 25 / 703;
        outputLabel.setText(name + " , your ideal weight is " + weight + " lbs");
    }
    else{
        outputLabel.setText("Error. Check your System input and try again.");
    }
}
