Rollable Tables Calculating Weights

Alright I am trying to figure out the best way to calculate weights to input into a rollable table, an example on the GURPS Roll20 Wiki entry there is a rollable table with the weights down at the bottom.however it doesn't equal 100%. I did find other sites the can do the calculation for me however they are in fractions of a % and I am unable to input decimals for the weight.

Multiply the values until you reach whole numbers. Example: if one of the weights is 12.5% then multiple everything by 10 and use 12.5% = 125 as your weighting. If you could be more specific I might be able to provide better advice.

Alright I guess my main question is if there is a requirement on the weights and what they equal up to. On the Roll20 Wiki for Rollable Tables it states that it must add up to 100, however withing the GURPs section it stats the maximum must equal 6 to the power of 3 for a total of 216. Using AnyDice and multiplying the probability percentage by 2.16 it pretty much equals what the GURPs table suggests.

You should convert it to a percentage and then multiply that by a factor of 10 until you get a number without a decimal. Then use that number as the weighting. Example...if you have 1/216 that is 0.004629...... A close approximation is 0.00463. Multiply that by 100000 to get a whole number which gives you a weighting of 463. Note: in this example there are 215 other options that equal 216 out of 216. If you want, send me a join link and then post your chart in your game and I can help you work out the weighting.

Doh, sometimes I make something simple complicated. :) So to expand on what Riley was saying, if you have an object that can happen 6 out of 216 times then giving it a weighting of 6 is what you need to do (assuming you give everything a weighting that totals up to 216).
