Wire sections: AWG, kcmil, mm² - JMB - 09-08-2018 05:24 PM
Here are four functions to convert wire sections between kcmil and mm², and between AWG and mm²
PHP Code:
EXPORT kcmil_to_mm2(kcmil)
// kcmil: section in kcmil → section in mm²
BEGIN
RETURN kcmil*0.506707479098;
END;
EXPORT mm2_to_kcmil(mm2)
// mm2: section in mm² → section in kcmil
BEGIN
RETURN mm2/0.506707479098;
END;
EXPORT AWG_to_mm2(AWG)
// AWG: AWG number → section in mm²
// 0, -1, -2 and -3 must be entered for AWG numbers 1/0, 2/0, 3/0 and 4/0
BEGIN
RETURN 53.4751207321/(92^(AWG/19.5));
END;
EXPORT mm2_to_AWG(mm2)
// mm2: section in mm² → nearest AWG number
// results 0, -1, -2 and -3 are equivalent to AWG numbers 1/0, 2/0, 3/0 and 4/0
BEGIN
RETURN ROUND(4.31245284200*LN(53.4751207321/mm2),0);
END;
Example 1: kcmil_to_mm2(300) returns 152.0122
Example 2: mm2_to_kcmil(150) returns 296.0288
Example 3: AWG_to_mm2(14) returns 2.0810
Example 4: mm2_to_AWG(4) returns 11
