Why is django-money running incorrectly in my view?

I'm using django-money to make conversions on my backend of the project but it is converting wrong. For example, I want to convert TRY to USD: I enter 1000000 TRY it returns 480629.66 USD, but it should be: 120055.20 USD. And when I enter 10000 Euro it returns 13677.61 USD but it should return 12139,25 USD.

How can I solve it?

views.py

def customer(request):
    form_class = NewCustomerForm
    current_user = request.user
    userP = UserProfile.objects.get_or_create(username=current_user)
    company = userP[0].company
    if request.method == 'POST':
        # Create a form instance and populate it with data from the request (binding):
        form = NewCustomerForm(request.POST)
        # Check if the form is valid:
        if form.is_valid():
            newCustomer = form.save()
            newCustomer.company = company
            selected_currency = newCustomer.currency_choice
            selected_limit = newCustomer.credit_limit
            newCustomer.usd_credit_limit = convert_money(Money(selected_limit, selected_currency), 'USD')
            cred_limit = newCustomer.usd_credit_limit
            value = str(cred_limit)[1:]
            # float_str = float(value)
            float_str = float(cred_limit.amount)
            newCustomer.credit_limit = float_str
            newCustomer.save()
            return redirect('user:customer_list')
    else:
        form = form_class()

    return render(request, 'customer.html', {'form': form})

You are using 2017/01/01 exchange rates. Read the api link carefully. You should update your exchange rates.

    from djmoney.contrib.exchange.backends import FixerBackend, OpenExchangeRatesBackend
    from djmoney.contrib.exchange.models import get_rate
    OpenExchangeRatesBackend().update_rates()
    FixerBackend().update_rates()
    get_rate('USD', 'EUR', backend=OpenExchangeRatesBackend.name)
    get_rate('USD', 'EUR', backend=FixerBackend.name)

or you can update like :

    $ python manage.py update_rates
    Successfully updated rates from openexchangerates.org
    $ python manage.py clear_rates
    Successfully cleared rates for openexchangerates.org

You can also access the exchange rates on the admin page in default.
