Converting USD to Robux can be tricky given how much the exchange rate fluctuates. However, the most reliable benchmark is the DevEx rate. Short for Developer Exchange, DevEx is a documented Roblox system that allows creators to cash out their virtual currency for real money. As of today, the rate is set at $0.0038 per Robux. We use this standard for all our conversions, while applying a few subtle adjustments to ensure ongoing accuracy.

How it works?

Converting USD to Robux

The formula for this is quite easy, it is simply dividing the price in USD by the actual Robux rate, which looks like this for example:

let priceUsd: number = 10;
let rateRobux: number = 0.0038;

let priceRobux: number = priceUsd / rateRobux;
console.log(priceRobux);
// Output: 2631.5789

let priceUsd = 10;
let rateRobux = 0.0038;

let priceRobux = priceUsd / rateRobux;
console.log(priceRobux);
// Output: 2631.5789

priceUsd = 10
robuxRate = 0.0038

priceRobux = priceUsd / robuxRate
print(priceRobux)
# Output: 2631.5789

Rounding to the greatest integer

At this point, we got our price in Robux, but… Roblox don’t like decimals and needs us to use integers, so we round the value to the greatest integer, which would result in:

let priceRobux: number = 2631.5789

let rounded: number = Math.ceil(priceRobux)
console.log(rounded);
// Output: 2632

let priceRobux = 2631.5789

let rounded = Math.ceil(priceRobux)
console.log(rounded);
// Output: 2632

import math
priceRobux = 2631.5789

rounded = math.ceil(priceRobux)
print(rounded)
# Output: 2632
