How to calculate a 1.45 liter cup to be 0.6 liter

[TMicke 19]

I have a model of a 1.45 liter cup, how do i calculate it to be a 0.6 liter cup?

 

lets just say that it wasn’t just my history teacher that cried 😂

In Fusion360 there is a function to calculate the volume (of water).

I guess I wasn’t clear enough.

 

-If I have a model of a cup that holds 1.45L and I wish to resize it in Cura so that it prints a cup holding 0.6L ; how do I make that calculation? (By hand of course)

Ahh ok, got it 🙂

Maybe this helps https://www.calculator.net/volume-calculator.html

Roughly scale with 0,745 , or more exact, sqrt3 (0,6/1,45)  

"Tredje roten ur..." in our language 😉

See, thats the problem, can't even recalling ever heard 'tredje roten ur' 😄 Men alltid kul att läsa lite svenska...

 

I guess I'm out of my league here, but is that (sqrt3 (0,6/1,45)) the actual formula. I'm mostly thinking of of that 'sqrt3' thingie. Or is this solvable with just multiplying and/or dividing?

 

*I guess I don't make a lot of sense due to my ignorance. I looked at my calculator and found that sqrt3 function and managed to get the result you gave me so hopefully I can remember this.

 

Thank you Anders!

sqrt3 is a bit of a strange name: Whereas sqrt is short for square root, sqrt3 is actually the cube root.

 

Square root of a value is the inverse function of square of a value: sqrt(value * value) = value.

Cube root of a value is the inverse function of the cube of a value: sqrt3(value * value * value) = value.

Newbie tutorial (written with myself in mind):

 

On your calculator type in the following:

0.6

/

1.45

And now press button marked in image below

I didnt know the phrase in english so thanks for the lesson. 

(Even though math are considered to be the common language of the universe 😄)

 

Cube root what was I was looking for, hence writing it in our native language too...
