I found the command. I used df but this is what happened after I tried to format it:

$ sudo mkfs /dev/sdc

mke2fs 1.42.9 (4-Feb-2014)

/dev/sdc is entire device, not just one partition!

Proceed anyway? (y,n) y

mkfs.ext2: No medium found while trying to determine filesystem size

What is wrong?

I want to use this card. Currently it is partitioned. Can I delete all of the partitions by formatting it with mkfs? I would have just tried it without asking but I can't remember what the command is to see what number the device has been assigned (/dev/sd??) so I need help with that as well.
