You probably want
maskedImage = binaryImage .* originalImage;

For the future, this operation is called "masking", not "converting" of a binary image to a gray scale image. If original image is an integer, you need to cast binary image to the same class of integer, like
maskedImage = uint8(binaryImage) .* originalImage;
Or initialize and then use the binary image as indexes:
maskedImage = originalImage; % Initialize
maskedImage(~binaryImage) = 0; % Mask

Try this:
binaryImage = grayImage;
Your (formerly) binary image will now be converted into the same array as your gray scale image, so it's now a gray scale image, not a binary image anymore.
