SUMMARY

A megabyte (MB) consists of 1,024 kilobytes (KB) when using binary measurement, which is the standard in computing. This is often referred to as a kibibyte (KiB) to distinguish it from the decimal measurement where 1 MB equals 1,000 KB. For example, 178,000 KB translates to approximately 173.8 MB in binary terms. The discrepancy arises because storage devices may advertise sizes based on decimal calculations, leading to confusion regarding actual usable space.

PREREQUISITES
  • Understanding of binary vs. decimal measurement systems
  • Familiarity with data storage terminology
  • Basic knowledge of computer memory units
  • Awareness of marketing practices in storage device specifications
NEXT STEPS
  • Research the differences between binary and decimal data measurements
  • Learn about the International Electrotechnical Commission (IEC) standards for data measurement
  • Explore how operating systems report disk space and memory
  • Investigate the implications of storage marketing on consumer expectations
USEFUL FOR

This discussion is beneficial for computer science students, IT professionals, and anyone involved in data management or storage solutions who seeks to understand the nuances of data measurement and its practical implications.

simple questions:

How many kilobtyes are in a megabyte, and how do you explain this?

and

If i have, let's say, 178,000 kilobytes how many megabytes would this translate to? and how can it be explained?

It's a tricky question.
Technically kilo means 1000 and mega means 1,000,000
But in computers it's often easier to talk about multiples of 1024 so in general speak a kilobyte is 1024 bytes. Techncially this should be called a kibobyte (kibo=1024).

Then you get into marketing speak, hard drives that are sold as 100Mega bytes will often be 100,000,000 bytes - the computer working in kibobytes will list this as only 95Mb ie. 100,000,000 / (1024*1204)

So 178,000kb could be 178Mb or 173.8Mb depending
