To remember the table, one starts with the well known fact that 32 degrees Farenheit is freezing temperature for water, which is also 0 degrees Celsius. Now note the following:
From this one can easily construct the rest of the table.
It is also worthwhile to notice that the sum of the two digits for the Farenheit temperatures in the table is always 5 or 14.
For instance, to find the Farenheit value corresponding 35 degrees celsius, the steps are as follows:
It is worth knowing that 60 degrees Celsius corresponds to 140 degrees Farenheit. This is the maximum temperature most people would want to use for dishwaters or washing machines.
If one is unfortunate enough to have to deal with temperatures below freezing, here is a table. Note that in this table, the digits of negative Farenheit temperatures in the table add up to 4 or 13.
To convert a two-digit number ending in 5 from kilos to pounds, double the tens digit, then multiply by 11. If then original number ends in 0, then this is the answer. But if the original number ends in 5, add 11 once more.
For instance, the conversion for 65 kilos is as follows:
|6 *2 = 12||12 * 11 = 132||132 + 11 = 143|
