This method avoids overlooking the <a href="/wiki/Decimal_separator" title="Decimal separator">decimal separator</a>, which may not be rendered reliably on components or when duplicating documents. The standards also define a <a href="/wiki/Color_code_for_fixed_resistors" class="mw-redirect" title="Color code for fixed resistors">color code for fixed resistors</a>. <div class="mw-heading mw-heading2"><h2 id="Part_value_code">Part value code</h2>[<a href="/w/index.php?title=RKM_code&action=edit&section=2" title="Edit section: Part value code">edit</a>]</div> <table class="wikitable floatright"> <caption>Examples of resistance values<a href="#cite_note-ETB_2010-11">[11]</a> </caption> <tbody><tr> <td>R47 </td> <td>0.47 <a href="/wiki/Ohm" title="Ohm">ohm</a> </td></tr> <tr> <td>4R7 </td> <td>4.7 ohm </td></tr> <tr> <td>470R </td> <td>470 ohm </td></tr> <tr> <td>4K7 </td> <td>4.7 <a href="/wiki/Kilohm" class="mw-redirect" title="Kilohm">kilohm</a> </td></tr> <tr> <td>47K </td> <td>47 kilohm </td></tr> <tr> <td>47K3 </td> <td>47.3 kilohm </td></tr> <tr> <td>470K </td> <td>470 kilohm </td></tr> <tr> <td>4M7 </td> <td>4.7 <a href="/wiki/Megohm" class="mw-redirect" title="Megohm">megohm</a> </td></tr> </tbody></table> For brevity, the notation omits to always specify the unit (<a href="/wiki/Ohm" title="Ohm">ohm</a> or <a href="/wiki/Farad" title="Farad">farad</a>) explicitly and instead relies on implicit knowledge raised from the usage of specific letters either only for resistors or for capacitors,<a href="#cite_note-NB_Letter-M-12">[nb 1]</a> the case used (uppercase letters are typically used for resistors, lowercase letters for capacitors),<a href="#cite_note-NB_Letter-Case-13">[nb 2]</a> a part's appearance, and the context. The notation also avoids using a <a href="/wiki/Decimal_separator" title="Decimal separator">decimal separator</a> and replaces it by a letter associated with the prefix symbol for the particular value.<a href="#cite_note-NB_DecimalSeparator-14">[nb 3]</a> This is not only for brevity (for example when printed on the part or PCB), but also to circumvent the problem that decimal separators tend to "disappear" when <a href="/wiki/Photocopy" class="mw-redirect" title="Photocopy">photocopying</a> printed circuit diagrams. Another advantage is the easier sortability of values which helps to optimize the <a href="/wiki/Bill_of_materials" title="Bill of materials">bill of materials</a> by combining similar part values to improve maintainability and reduce costs.<a href="#cite_note-NB_Sortability-15">[nb 4]</a> The code letters are loosely related to the corresponding <a href="/wiki/SI_prefix" class="mw-redirect" title="SI prefix">SI prefix</a>, but there are several exceptions, where the capitalization differs or alternative letters are used. For example, <code>8K2</code> indicates a resistor value of 8.2 kΩ. Additional zeros imply tighter tolerance, for example <code>15M0</code>.<a href="#cite_note-Rohm_2024-16">[12]</a> When the value can be expressed without the need for a prefix, an <code>R</code> or <code>F</code> is used instead of the decimal separator. For example, <code>1R2</code> indicates 1.2 <a href="/wiki/Ohm" title="Ohm">Ω</a>, and <code>18R</code> indicates 18 Ω. <table class="wikitable"> <tbody><tr> <th colspan="2">Code letter </th> <th colspan="2"><a href="/wiki/SI_prefix" class="mw-redirect" title="SI prefix">SI prefix</a> </th> <th colspan="2">Multiplier<a href="#cite_note-Tooley_2011-17">[13]</a> </th></tr> <tr> <th>Resistance [<a href="/wiki/Ohm_(unit)" class="mw-redirect" title="Ohm (unit)">Ω</a>] </th> <th>Capacitance [<a href="/wiki/Farad_(unit)" class="mw-redirect" title="Farad (unit)">F</a>] </th> <th>Name </th> <th>Symbol </th> <th>Base 10 </th> <th>Value </th></tr> <tr> <td>— </td> <td>p (P<a href="#cite_note-NB_Letter-Case-13">[nb 2]</a><a href="#cite_note-NB_Letters-P-N-18">[nb 5]</a>) </td> <td>pico </td> <td>p </td> <td>× 10−12 </td> <td>× 0.000000000001 </td></tr> <tr> <td>— </td> <td>n (N<a href="#cite_note-NB_Letter-Case-13">[nb 2]</a><a href="#cite_note-NB_Letters-P-N-18">[nb 5]</a>) </td> <td>nano </td> <td>n </td> <td>× 10−9 </td> <td>× 0.000000001 </td></tr> <tr> <td>— </td> <td>μ (u, U<a href="#cite_note-NB_Letter-Case-13">[nb 2]</a>) </td> <td>micro </td> <td>μ </td> <td>× 10−6 </td> <td>× 0.000001 </td></tr> <tr> <td>L </td> <td>m (M<a href="#cite_note-NB_Letter-M-12">[nb 1]</a><a href="#cite_note-NB_Letter-Case-13">[nb 2]</a>) </td> <td>milli </td> <td>m </td> <td>× 10−3 </td> <td>× 0.001 </td></tr> <tr> <td>R (E<a href="#cite_note-NB_Letter-E-19">[nb 6]</a>) </td> <td>F </td> <td>— </td> <td>— </td> <td>× 100 </td> <td>× 1 </td></tr> <tr> <td>K (k<a href="#cite_note-NB_Letter-k-20">[nb 7]</a>) </td> <td>— </td> <td>kilo </td> <td>k </td> <td>× 103 </td> <td>× 1000 </td></tr> <tr> <td>M<a href="#cite_note-NB_Letter-M-12">[nb 1]</a> </td> <td>— </td> <td>mega </td> <td>M </td> <td>× 106 </td> <td>× 1000000 </td></tr> <tr> <td>G </td> <td>— </td> <td>giga </td> <td>G </td> <td>× 109 </td> <td>× 1000000000 </td></tr> <tr> <td>T </td> <td>— </td> <td>tera </td> <td>T </td> <td>× 1012 </td> <td>× 1000000000000 </td></tr></tbody></table> For resistances, the standard dictates the use of the uppercase letters <code>L</code> (for 10−3), <code>R</code> (for 100 = 1), <code>K</code> (for 103), <code>M</code> (for 106), and <code>G</code> (for 109) to be used instead of the decimal point.<a href="#cite_note-Rohm_2024-16">[12]</a> The usage of the letter <code>R</code> instead of the SI unit symbol Ω for ohms stems from the fact that the Greek letter Ω is absent from most older <a href="/wiki/Character_encoding" title="Character encoding">character encodings</a> (though it is present in the now-ubiquitous <a href="/wiki/Unicode" title="Unicode">Unicode</a>) and therefore is sometimes impossible to reproduce, in particular in some CAD/CAM environments. The letter <code>R</code> was chosen because visually it loosely resembles the Ω glyph, and also because it works nicely as a <a href="/wiki/Mnemonic" title="Mnemonic">mnemonic</a> for resistance in many languages.[<a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed">citation needed</a>] The letters <code>G</code> and <code>T</code> weren't part of the first issue of the standard, which pre-dates the introduction of the <a href="/wiki/SI_system" class="mw-redirect" title="SI system">SI system</a> (hence the name "RKM code"), but were added after the adoption of the corresponding SI prefixes. The introduction of the letter <code>L</code> in more recent issues of the standard (instead of an <a href="/wiki/SI_prefix" class="mw-redirect" title="SI prefix">SI prefix</a> <code>m</code> for <a href="/wiki/Milli-" title="Milli-">milli</a>) is justified to maintain the rule of only using uppercase letters for resistances (the otherwise resulting <code>M</code> was already in use for <a href="/wiki/Mega-" title="Mega-">mega</a>). Similar, the standard prescribes the following lowercase letters for capacitances to be used instead of the decimal point: <code>p</code> (for 10−12), <code>n</code> (for 10−9), <code>μ</code> (for 10−6), <code>m</code> (for 10−3), but uppercase <code>F</code> (for 100 = 1) for <a href="/wiki/Farad" title="Farad">farad</a>. The letters <code>p</code> and <code>n</code> weren't part of the first issue of the standard, but were added after the adoption of the corresponding SI prefixes. In cases where the Greek letter <code>μ</code> is not available, the standard allows it to be replaced by <code>u</code> (or <code>U</code>, when only uppercase letters are available).
