File Sizes Conversion File sizes can be very confusing. For instance - which is bigger? 1.2 MB or 1200 KB? They are basically the same size! Confused? There is no need to be! File sizes can be very confusing. For instance - which is bigger? 1.2 MB or 1200 KB? They are basically the same size! Confused? There is no need to be! Each unit changes names when you get to 1000 of that unit. The basic unit is a byte. If you have 1000 bytes, you can then call it 1 kilobyte. If you have 1000 kilobytes, you can then call it 1 megabyte. The same happens when you go up from megabytes to gigabytes. Each unit changes names when you get to 1000 of that unit. The basic unit is a byte. If you have 1000 bytes, you can then call it 1 kilobyte. If you have 1000 kilobytes, you can then call it 1 megabyte. The same happens when you go up from megabytes to gigabytes. Note that the decimal place moves three places either to the right or left. Note that the decimal place moves three places either to the right or left.

Converting from One Measurement to Another (1) To convert from a larger to the next smaller unit, just move the decimal place three places to the right. For instance: If you have 1 gigabyte, how many megabytes are there? To convert from a larger to the next smaller unit, just move the decimal place three places to the right. For instance: If you have 1 gigabyte, how many megabytes are there? The answer is 1 GB = 1,000 MB.

Converting from One Measurement to Another (2) To convert from a smaller unit to the next larger unit, move the decimal place three places to the left. For instance: If you have 1,000 kilobytes, how many megabytes are there? To convert from a smaller unit to the next larger unit, move the decimal place three places to the left. For instance: If you have 1,000 kilobytes, how many megabytes are there? The answer is 1,000 KB = 1 MB.
