Pak Indra, ini kiriman dari teman mungkin bisa menjelaskan..... dari:
http://www.unc.edu/~rowlett/units/dictO.html *ons* a Dutch unit of weight or mass, now used as a metric unit equal to the hectogram (100 grams, or about 3.5274 ounces). *ounce (oz or oz av) [1]* a traditional unit of weight. The *avoirdupois ounce*, the unit commonly used in the United States, is 1/16 pound or about 28.3495 grams. The avoirdupois ounce also equals 175/192 == about 0.911 457 troy ounce or 437.5 grains <http://www.unc.edu/%7Erowlett/units/dictG.html#grain>. The word ounce is from the Latin /uncia/, meaning a 1/12 part, because the Roman pound was divided into 12 ounces. The word "inch," meaning 1/12 foot, has the same root. The symbol oz is from the old Italian word /onza/ (now spelled /oncia/) for an ounce. See avoirdupois weights <http://www.unc.edu/%7Erowlett/units/dictA.html#avoirdupois> for additional information. http://www.unc.edu/~rowlett/units/dictP.html *pond [1]* the Dutch pound, historically about 494 grams (1.089 English pounds). This unit was also used in the former Dutch Indies (now Indonesia) and throughout Southeast Asia. In the Netherlands, the pond has been reinterpreted now as a metric unit equal to exactly 500 grams (1.1023 pounds), like the German pfund. *pound (lb, lbm, or #) [1]* a traditional unit of mass or weight. The Romans used a pound (the /libra //pondo/, "pound of weight") divided into 12 ounces. All the countries of western Europe used similar units, divided into 12 or 16 ounces, until the advent of the metric system. 12-ounce pounds were common in Italy and southern France, but in Spain and northern Europe 16-ounce pounds became the norm. The word libra <http://www.unc.edu/%7Erowlett/units/dictL.html#libra> is used for this unit in Italy, Spain, and Portugal; in France it is called the livre <http://www.unc.edu/%7Erowlett/units/dictL.html#livre <http://www.unc.edu/%7Erowlett/units/dictL.html#livre> >. Further north, the Latin word /pondo/ ("weight") is the origin of the names of the English pound, Dutch pond, Danish pund, German pfund, and Russian funt. In England, two different "pound" units became standard. The unit now in general use in the United States is the *avoirdupois pound*, so-called from a French phrase /avoir du poids/, literally "goods of weight," indicating simply that the goods were being sold by weight rather than by volume or by the piece. The avoirdupois pound is divided into 16 ounces <http://www.unc.edu/%7Erowlett/units/dictO.html#ounce>. By international agreement, one avoirdupois pound is equal to exactly 453.592 37 grams; this is exactly 175/144 == 1.215 28 troy pounds. See avoirdupois weights <http://www.unc.edu/%7Erowlett/units/dictA.html#avoirdupois> for additional information. The traditional symbol *lb* stands for /libra/, the Latin word for the unit. The avoirdupois pound is sometimes abbreviated *lb av* or *lb ap* to distinguish it from the less common troy pound.The symbol *lbm* is used in science to distinguish the pound of mass from the pound of force (lbf): see *pound force*, below. Kesimpulan saya, CMIIW: Tak salah kalau orang Indonesia mengatakan 1 ons == 100 gr, seperti kalau kita belanja dipasar. Karena hal ini memang sudah umum, dan memang benar ini kita warisi dari Belanda. Cuman masalahnya apa terjemahan Inggris-Indonesia dari ounce? Biar tidak ambigu, mungkin ounce tak usah diterjemahkan ke ons, tapi cukup 1 ounce == 28,35 gr. Toh saya rasa hanya kalangan tertentu (engineering, scientist) yang menggunakan istilah ounce. Itu juga sama dengan pound, kita juga tak pernah menggunakan pound, or do we? Dan pon yang dikenal oleh umumnya kita memang, 1 pon == 500 gr, sama persis, kita mewarisinya dari Belanda, dan sudah dimodifikasi dari asalnya pond == 494 gr. So biarlah orang umum di Indonesia menggunakan: 1 ons == 100 gr 1 pon == 500 gr jadi 1 pon== 5 ons. Dengan ini, Ibu-ibu yang suka belanja nggak perlu bakal bingung.:) tetapi untuk keperluan tertentu yang menggunakan ounce atau pond, 1 ounce == 28.35 gr 1 pound == 453,6 gr Barangkali kendala untuk 2 yang terakhir ini adalah terjemahan ke bahasa Indonesia, mungkin ini yang perlu dicari bersama. Wallahua'lam. -----Original Message----- From: Diannanjaya, Indra I [mailto:[EMAIL PROTECTED] Sent: Thursday, April 28, 2005 9:08 AM To: [email protected] Subject: [exbhp] Re: Fwd: [Oil&Gas] (OOT) 1 ONS BUKAN 100 GRAM Isu ini benar2 faktual karena baru saja tadi malam saya menemani anak saya belajar untuk ulangan matematika kls 3 SD dimana sangat kebetulan topiknya adalah mengenai perhitungan berat. Dalam buku wajib, jelas dikatakan 1 kg = 10 ons alias 1 ons = 100 gram. Ini benar2 membuat saya tersadar, dan langsung mengecek semua "mesin" konversi saya dan memang betul apa yg dikatakan dalam imel ini, bahkan istilah ounce itu ada 2 yaitu Avoirdupois Ounce dan Troy Ounce yang nilai konversinya sedikit berbeda. Saya jadi teringat setiap minggu menemani istri belanja di pasar, semua pedagang memakai isitilah ons dan anak timbangan juga memakai ons!! Why bother?? Mungkin bagi sebagian orang isu ini tidak penting tapi menurut saya isu ini mirip dengan penggunaan koma dan titik dalam penulisan angka ribuan. Setahu saya hampir seluruh dunia menuliskan angka seribu dengan 1,000 tapi di Indonesia ditulis 1.000. Semua kalkulator dan komputer tidak mengenal sistem ini. Perusahaan2 asing sering mendapatkan masalah dalam penulisan laporannya kepada pemerintah karena memakai sistem yang baku sedangkan pemerintah Indonesia memakai sistem yang kebalikannya. Tulisan ini sudah saya print dan kemungkinan akan saya diskusikan dengan guru sekolah anak saya. Thanx Bang Awin. -----Original Message----- From: shobirin mohammad [mailto:[EMAIL PROTECTED] Sent: Wednesday, April 27, 2005 11:39 PM To: [email protected] Subject: [exbhp] Fwd: [Oil&Gas] (OOT) 1 ONS BUKAN 100 GRAM All, Ini ada diskusi menarik dr milis tetangga... jangan sampe kita salah itung trus kena PHK.. true story!! ---------- Forwarded message ---------- From: Ferry Triyana <[EMAIL PROTECTED]> Date: Apr 25, 2005 9:09 AM Subject: [Oil&Gas] (OOT) 1 ONS BUKAN 100 GRAM To: [EMAIL PROTECTED] 1 ONS BUKAN 100 GRAM. =============================================== The content of this message may contain the private views and opinions of the sender and does not constitute a formal view and/or opinion of the company unless specifically stated.
