  1. Multiway HTML-Entities Translator improved!
  2. Multiway Logarithm Calculator improved!

» This page may be the most useful page that you can get out of my whole site (and most stuffed too)! Enjoy it.

These are the most useful
Calculators and Converters I've created - only by using JavaScript.

Temperature Converters

First of all, Meet the bad boys...

°F - (Degrees) Fahrenheit
°C - (Degrees) Celsius
K - Kelvin
°Ra - (Degrees) Rankine

...And now, the converters!

NOTES:

  1. Please only enter numbers... or the calculator will generate faulty answers or a “NaN” (Not-a-Number) OR “undefined”.
  2. Answers that are too big for the calculator will be displayed as “Infinity” - but usually it's not really as big as Infinity (∞).
  3. Inserted operators (i.e.: + - * /) can be used, but watch out when doing some divisions.
    (i.e.: 1/0 makes the calculator gives an answer of “Infinity” when it's supposed to be undefined.)
  4. If possible, answers are rounded to 2 decimal places/the nearest hundredths.
  5. Entering values at either fields WILL work.
  6. Sample values had been put in (when the page first loads).
  7. Answers are automatically updated when:
    • Keyboard is pressed while one of the fields is active.
    • One of the fields is clicked/activated, and once the field is left/deactivated.

HTML entity codes picker

There are some pretty cool and useful symbols that can be used from HTML entities! The problem is you might not know what the specific entity code you'll need to create a symbol that you want to use. This entity symbol/generator + some useful symbol picker might be a help.

Please enter the entity range to view: &#; to &#;  |OR|  Pick:
