Tuma maandishi kwa Hex

Badilisha maandishi kuwa uwakilishi wa hexadecimal bila kujitahidi

Chombo cha kubadilisha fedha

0 characters

Enter text to convert to hexadecimal. Choose between UTF-8 (supports all characters) and ASCII (only 128 characters). Options to add spaces between hex values and use uppercase letters are available.

Usimbaji wa maandishi

Herufi za maandishi zinawakilishwa na nambari kwenye kompyuta. Mifumo tofauti ya usimbuaji hutumia nambari tofauti kwa wahusika:

ASCII

The ASCII (American Standard Code for Information Interchange) encoding uses 7 bits to represent 128 characters, including English letters (both uppercase and lowercase), digits, and common punctuation symbols. Each ASCII character can be represented by a unique number between 0 and 127.

UTF-8

UTF-8 ni usimbaji wa herufi za urefu tofauti ambao unaweza kuwakilisha kila herufi katika kiwango cha Unicode. Inatumia ka 1 hadi 4 kwa kila mhusika. UTF-8 inaendana nyuma na ASCII, ikimaanisha kuwa herufi 128 za kwanza za UTF-8 zinafanana na ASCII.

Mchakato wa Ubadilishaji

Kubadilisha maandishi kuwa hexadecimal kunahusisha hatua zifuatazo:

  1. Determine the numerical value of each character using the chosen encoding (ASCII or UTF-8).
  2. Convert each numerical value to its hexadecimal (base-16) representation.
  3. Kwa hiari, tenganisha kila thamani ya hexadecimal na nafasi ya usomaji.
  4. Kwa hiari, badilisha herufi zote za hexadecimal kuwa herufi kubwa.

Mfano: Badilisha "Hi" kuwa Hexadecimal

Step 1: Convert each character to its numerical value (ASCII):

H → 72

i → 105

Hatua ya 2: Badilisha kila thamani ya nambari kuwa hexadecimal:

72 → 48 (in hexadecimal)

105 → 69 (in hexadecimal)

Step 3: Combine the hexadecimal values (with spaces):

48 69

Vidokezo vya Matumizi

  • When using ASCII encoding, any character outside the 7-bit ASCII range (128-255) will be converted to a question mark (?).
  • Usimbaji wa UTF-8 unaauni herufi zote za Unicode, ikiwa ni pamoja na alama maalum, emoji na herufi kutoka lugha zisizo za Kiingereza.
  • Kila herufi ya UTF-8 inaweza kuwakilishwa na maadili mengi ya hexadecimal ikiwa inatumia zaidi ya baiti moja.
  • Thamani za hexadecimal mara nyingi hutumiwa katika kompyuta kwa anwani za kumbukumbu, misimbo ya rangi, na uwakilishi wa data ya binary.
