So there are 1.000 MB in a GB in decimal. And in binary base there are 1024 MB in a GB.

If you are talking about decimal (SI), 1000 MB is equal to 1 GB. On the other hand, 1 GB is equal to 1.024 MB in binary.

In pure computer terms 1GB = 1024MB. The decimal system has come from tech manufacturers deciding that it was easier for consumers to understand multiplying by 1000 rather than 1024. Back in the day, only computer professionals possessed computers so the 1024 KB system was second nature to them, as computers became more affordable and the layperson gained ownership, the decimal system was introduced as people were already familiar with kilometres and kilograms.

There are much confusion some where show that 1 tb is equal to 1000 GB and some where show that 1 GB is equal to 1024 GB.
