The Asian decimal system is used in regions including Southeast Asia and North Asia, where 6 or 7 digits are used to spell out large numbers. The system is also used in some parts of China mainly for business documents and contracts.

So often when dealing with countries and regions where the decimal system is used, it’s hard to work out how much 1 item is worth in comparison to another. If you are ever asked to convert from one currency to another, particularly if the amounts are not in multiples of 100, this can become a chore. Fear not, help is at hand, as this article will teach you how to calculate percentages using the Asian decimal system.

## Step one: Find the conversion rate.

The first step is to find the conversion rate for the two currencies. For the purposes of this example, we’ll use the Malaysian Ringgit (MYR) to Japanese Yen (JPY) rate which is available at https://www.xe.com/ucc/currencies. The value of 1 Ringgit in yen is currently $0.0127. If you wish to convert 1,000 Malaysian Ringgit into Japanese yen, then multiply 0.0127 by 1000 to find the value in yen, which is 126,827.50.

## Step two: Find the price in Malaysian Ringgit.

We then need to find the price in Malaysian Ringgit for the item or items we are exchanging. In this case, it’s pretty easy, though you might want to do a little bit of research first if you’re not sure whether or not you’re going to sell the item. We’ll use the BMW motorbike as an example. It is currently available for purchase in Malaysia for 399,000 ringgit. We’ll use 399,000 as the input value for the search box, and hit enter.

The output shows a variety of different BMW motorbikes, with the best price being 399,000 ringgit. This means that for every 100 Japanese yen the buyer is paying, the seller is getting 100 Malaysian Ringgit in return. We can round this off to the nearest whole number by hitting CTRL+J/COMMA on a Mac, and it will bring us back to the “$0.00” prompt. If we wish to sell the BMW motorbike for 400,000 Japanese yen, then we simply input 400,000 as the new price and hit enter.

We can round this number up to the nearest whole number by hitting enter on a Mac, and it will bring us back to the “$0.00” prompt. For the purposes of this example, let’s assume that we want to sell the bike for 450,000 Japanese yen, so we type this in and hit enter.

## Step three: Calculate the percentage increase or decrease in value.

Let’s now calculate the percentage increase or decrease in value of the BMW compared to when it was priced at 399,000 ringgit. The calculation is simply:

(450,000 – 399,000) / 399,000 x 100 = 16.7% increase

If you’re feeling a little bit more adventurous, you can use this same technique to work out the percentage decrease in value of the bike compared to when it was first priced at 399,000 ringgit. In this case, the calculation is:

(450,000 – 399,000) / 399,000 x 100 = -19.8% decrease

## Step four: Calculate the final value in Japanese yen.

Finally, we need to calculate the final value in Japanese yen of the item we’ve been evaluating. In the first scenario, the motorcycle was originally priced at 399,000 ringgit, and we wish to sell it for 450,000 Japanese yen, so the final value is:

(450,000 – 399,000) + 126,827.50 x 100 = 5069.2777 Japanese yen

We can round this up to the nearest whole number by hitting CTRL+J/COMMA on a Mac, and it will bring us back to the “$0.00” prompt. In the second scenario, the motorcycle was originally priced at 400,000 ringgit, and we wish to sell it for 400,000 Japanese yen, so the final value is:

(400,000 – 399,000) + 126,827.50 x 100 = 1438.2777 Japanese yen

We can round this number up to the nearest whole number by hitting enter on a Mac, and it will bring us back to the “$0.00” prompt.
