  • What are the common memory measurement units discussed in this material?
    Kilobytes, megabytes, gigabytes
  • How many kilobytes are in a megabyte (MB)?
    1,000 KB
  • How many megabytes are in a gigabyte (GB)?
    1,000 MB
  • How many kilobytes are in 2.5 megabytes (MB)?
    2,500 KB
  • What is 2.5 MB converted to kilobytes (KB)?
    2,500 KB
  • To convert 2.5 MB to KB, you multiply by 1,000.
  • What is the size of a 3,500-byte file in kilobytes (KB)?
    3.5 KB
  • What is the size of a 3,500,000-byte file in megabytes (MB)?
    3.5 MB
  • A file that is 3,500,000 bytes in size would be 3.5 MB.
  • A gigabyte (GB) is equal to 1,000,000,000 bytes.
    True
  • How many kilobytes (KB) are in a megabyte (MB)?
    1,000
  • Convert 2.5 MB to KB.
    2,500 KB
  • What calculation is used to convert bytes to kilobytes?
    Bytes ÷ 1,000 = KB
  • What calculation is used to convert bytes to megabytes?
    Bytes ÷ 1,000,000 = MB
  • 1 KB is equal to 1,000 bytes.
    True
  • A kilobyte (KB) is equal to 1,000 bytes.
  • A gigabyte (GB) is equal to 1,000,000 bytes.
    False
  • To convert from gigabytes (GB) to megabytes (MB), you multiply by 1,000.
  • To convert from larger units to smaller units, you multiply by 1,000.
  • What is 4 GB converted to megabytes (MB)?
    4,000 MB
  • How many bytes are in a megabyte (MB)?
    1,000,000 bytes
  • To calculate file sizes in kilobytes (KB) from bytes, you divide the number of bytes by 1,000.

    True
  • To calculate file sizes in megabytes (MB) from bytes, you divide the number of bytes by 1,000,000.
  • How many bytes are in a megabyte (MB)?
    1,000,000
  • How many bytes are in a kilobyte (KB)?
    1,000
  • To convert between memory units, you multiply or divide by 1,000.
  • Match the memory unit with its size:
    Kilobyte (KB) ↔️ 1,000 bytes
    Megabyte (MB) ↔️ 1,000 KB
    Gigabyte (GB) ↔️ 1,000 MB
  • 1 GB is equal to 1,000 MB.
  • A file that is 3,500 bytes in size would be 3.5 KB.
  • A file that is 5,000,000,000 bytes in size would be 5 GB.
  • Order the memory units from smallest to largest.
    1️⃣ Byte
    2️⃣ Kilobyte (KB)
    3️⃣ Megabyte (MB)
    4️⃣ Gigabyte (GB)
