Should there be a calorie symbol?

California recently passed a law requirement restaurants with more than 20 chains to post the calorie content of their food on menus and interior menu boards.

It’s a smart law, but it brings up an interesting issue: there’s no simple symbol for the calorie unit. This will clutter up boards and menus with “Cal.” listed all over the place. It seems like there’s a growing need for a calorie symbol. Here’s my rough suggestion:

From looking at other symbols like the at (@) or the pilcrow (¶), it seems important that the symbol be able to be handwritten as well as flexible for different typefaces. I thought the simple dot inside the upper case C implies eating or gestation.

Of course, we could fully adopt the International System and have to start all over with Joules.
