  • Character Conversions
    • ASCII Conversions
      Convert ASCII strings to and from: binary, hex, integers, and reverse. You may also convert ASCII to: lowercase, titlecase, and uppercase.
    • ASCII Table
      Shows the ASCII table with binary, decimal, hex, and octal equivalent values.
    • Key Codes
      Shows key value assigned to each key pressed on keyboard and their decimal values.
  • Extra Conversions
    • Animal Age
      Can determine animal age in human years and your age in animal years (cat, dog, and horse).
    • Depreciation
      Determine straight-line and sum of the years digits depreciation for the following...
      depreciation of year, overall depreciation, value of asset now. 10 years is the max.
  • File Download Time Conversions
      Shows amount of time a file(s) takes to download using a specific bandwidth service and/or speed from 9600 baud, to T-1, to OC-1 carriers, to the fastest there is called the DWDM (Dense Wave Division Multiplexor).
    • Small bandwidth common comparisons
      Units of measurement: bytes, kilobytes, megabytes, or gigabytes.
    • Medium bandwidth common comparisons
      Units of measurement: bytes, kilobytes, megabytes, or gigabytes.
    • Large bandwidth common comparisons
      Units of measurement: bytes, kilobytes, megabytes, or gigabytes.
    • Huge bandwidth common comparisons
      Units of measurement: bytes, kilobytes, megabytes, or gigabytes.
    • You Decide tab for specific speeds.
      Units of measurement: bytes, kilobytes, megabytes, or gigabytes.
      Speed types: bps (bits per sec), Bps (Bytes per sec), Kbps (Kilobits per sec), Mbps (Megabits per sec), Gbps (Gigabits per sec), Tbps (Terabits per sec).
  • Print and Image Conversions
    • PPI To Inches
      Determine the actual physical size of a digital image in inches.
    • File Size
      Determine the file size of a digital image.
    • PPI Needed For Scan
      Determine what PPI to scan an image at so you get the correct halftone when printing.
    • Effective Resolution Calculator (ERC)
      Effective resolution is the image resolution subsequent to scaling. Use this before scaling an image in a page layout program to determine it. If the calculated effective resolution doesn't meet your standards then either crop image in a photo editing program or rescan image at appropriate resolution and size intended for print.
    • Web Colors
      Convert Hex color values to RGB values and vise-versa, check whether a color is web-safe, and to show the nearest web-safe color.
  • Weather Conversions
    • Cricket Chirp Temperature
      Determine the temperature from number of cricket chirps heard. Fahrenheit, Celsius, Kelvin, and Rankine results.
    • dp/HI/RH
      Determine the dew point, heat index, and relative humidity. Celsius and Fahrenheit results.
    • Wind Chill
      Determine Wind Chill Index. Choices are pre-November 2001 and new formula. Fahrenheit only results.
  • Preferences capability for storing defaults such as number precision and window.
  • Help capability for assistance and definitions.
  • Check for new versions menu item. Allows you to both just check to see if newer version is available and see it's release notes or you can download it if available.
