'javascript how to set variables to be equal both ways?

I set some variables to make meters to feet ... let feet = meter * 3.280 but i have set meters = number also so i cant set meter = feet / 3.28 to get ther result that i want

how can i do that so it gives the right result?

in mathematics you can write meter <=> feet / 3.28

This is the wrong result that i get with my variables 2 meters=6.56feet| (2 feet=2 meters)

any help on how to structure it correctly? thank you

(it says i need for explanation to post this )......................................................................................................................................................................................................................................................................................................................................................................................................................................................................

let number = 2 
let meter = number
let feet = meter * 3.280
let calculate = document.getElementById("meterscalc")
document.getElementById("placenumber").textContent = number

function calc () {
   
    calculate.textContent = number +" meters=" + feet + "feet" + "|" + number + " feet=" + meter +" meters"
    
}

calc()
