#### WHAT IS THE PURPOSE OF CRAZY CALCULATIONS

INTRODUCTION
The idea behind this site is to make calculators which are very easy to use for interesting or useful calculations. Some of the calculators are very useful, some are educational some are just for fun.

If you want to see a calculator on this site which does not exist already you can request it using the calculation request link above. We never charge anything for making a calculator, it is all free. Below are recently added calculators.
Calculate how much sugar to add to increase the alcohol in wine
This page is for people who make wine where the original amount of sugar is not sufficient to make a storable wine (minimum 10% per volume) and therefore it is necesary to add sugar (chapitalise).The calculator on this page will enable you to make a fairly rough calculation accurate to within 1% alcohol by volume (ABV).

How long does the hot water last when taking a shower?
I sometimes have arguments with the rest of my family because there is often not enough hot water for us all to have a shower in the morning.

Can you calculate how long the water the water will last?
Get the driving route between any two places
I made this route maker so that I can send a link to anyone in our hiking group to show them how to get to the start of the walk. You can probably do this on a smartphone but I much prefer to do things with a laptop with a normal keyboard. Just type in the name of the start point and destination and a map will appear then click the link to make the link. Then copy the link into an email and sent it.
