2020-05-09 00:00:00 What's the question on everyone's mind during the great lockdown of 2020? "Where can I get toilet paper and how long will my stash last?" I can't answer the first question because I'm also looking for a solution (I'm open to suggestions, email the dev please). With this Simple Toilet Paper Calculator, you can calm your mind knowing exactly how long it will last. Unless you find you only have 7 days left, then you better hurry. By answering these four questions you'll be on your way to knowledge and power. How many rolls you have (TPR), how many sheets are in each roll (SPR), How many sheets are used per... bathroom usage (SPS), and your BURTs per Day (Bathroom Usages Requiring TP).
