跟一个米国counterpart来往了n多封邮件之后,才意识到那哥们对厘米毫米完全懵逼。好吧,我把所有尺寸都换算成英制发过去,那哥们才缓过神儿来。
米国人不用公制也罢,连换算都懒得弄,真是大爷啊。全世界都得随着他们转才成,服了。
12.7MM 是半英寸。在子弹上,漂亮国是使用公制的。
就这句话,你那个超光速大脑不理解就算了。

美国人很多基督教愚民相信圣经认为地球是平的。看报道说美国人比较傲慢,美国人不知道加拿大首都的比加拿大不了解美国人多。
说多伦多,温哥华的都有。
你罗里罗嗦说这么多没用, 美国人的弹药里的确有使用公制的,我又没说他们不使用英制。 Period.12.7MM 是半英寸。
美国从来就是叫 .50 机枪。 就是一寸的0.5。
我是不是错过了神马。

This article is about the .50 caliber M2 machine gun. For the Browning .30-06 machine gun, see M1919 Browning machine gun.
The M2 machine gun or Browning .50 caliber machine gun is a heavy machine gun designed toward the end of World War I by John Browning. Its design is similar to Browning's earlier M1919 Browning machine gun, which was chambered for the .30-06 cartridge. The M2 uses the much larger and much more powerful .50 BMG cartridge, which was developed alongside and takes its name from the gun itself (BMG standing for Browning machine gun). It has been referred to as "Ma Deuce",[8] in reference to its M2 nomenclature. The design has had many specific designations; the official US military designation for the current infantry type is Browning Machine Gun, Cal. .50, M2, HB, Flexible. It is effective against infantry, unarmored or lightly armored vehicles and boats, light fortifications, and low-flying aircraft.

The Browning .50 caliber machine gun has been used extensively as a vehicle weapon and for aircraft armament by the United States from the 1930s to the present. It was heavily used during World War II, the Korean War, the Vietnam War, the Falklands War, the Soviet–Afghan War, the Gulf War, the Iraq War, and the War in Afghanistan in the 2000s and 2010s. It is the primary heavy machine gun of NATO countries, and has been used by many other countries as well. The M2 has been in use longer than any other firearm in U.S. inventory except the .45 ACP M1911 pistol, also designed by John Browning.
The current M2HB is manufactured in the U.S. by General Dynamics[9] and U.S. Ordnance[10] for use by the U.S. government, and for allies via Foreign Military Sales, as well as by foreign manufacturers such as FN Herstal.
很少,通常是外来口径。
比如换成英寸是
.223XXX 他们就叫5.56mm
但 7.62MM ,他们一定会叫 .30
啥尺寸啊,要是对方把厘米的size认为毫米的size,那可糗大了。。。
接着吐苦水,你说用英制吧,楞有米国人不知道,一英尺等于多少英寸。
其实笑话都是相互的。我只是说有。多少关我屁事
而且,跟我一起打靶的老美,人家也说9mm,10mm的。没人傻逼嘻嘻的非要把所有都改成英制
