Directions

Type the number in the box and then click "Calculate"
If the number is 6.7 then type "6.7" (no quotation marks).
You may type the decimal point.
If the number is 2154 you may type "2,154", you may type the comma. Type "2,154".
If you want to type "256,678", but you type "25k,678", the computer will use "25678" to calculate the answer.
If you type "ghblxz", the computer will use "0" to calculate the answer.
If you type "1.9e2", the computer will use "190" to calculate the answer.

NaN = not a number

To clear the entry boxes click "Reset".

The light year calculation is based on the Julian year (365.25).
Julian year = 365.25 days
