That's right, and the tolerance on the amount is very small. For my large car (see the link below) it's 1,250g plus or minus 50g. So unless you have the equipment to evacuate the current gas and inject a weighed quantity of gas and measured quantity of oil then leave it to a professional.
Most areas are covered by mobile professionals who will do the recharge for between 50 and 80 quid depending on how much of their business appears on their tax returns. With this low cost, it's hardly worth spending money on equipment to DIY, especially on something that should only need doing every 5 years or so.
