有多少點來的同學可以不假思索地告訴我
111磅是多少斤?
不知道?
來來來,學習下
The pound or pound-mass is a unit of mass used in the imperial, United States customary and other systems of measurement. The most common today is theinternational avoirdupois常衡 pound, which is legally defined as exactly 0.45359237kilograms, and which is divided into 16 avoirdupois ounces盎司. The international standard symbol for the avoirdupois pound is lb. An alternative symbol is lbm (for most pound definitions). The unit is descended from the Roman libra (hence the abbreviation "lb").

所以,1lb≈0.45kg,換算成我們常用的說法就是1磅差不多是0.9斤的樣子。磅的表示符號,lb,也很好理解,因為它來自於羅馬字符libra,對的,就是天秤座的英文,天秤與重量單位有關,很好記。
另外,跟體重掛鈎的往往是身高
比如Kobe Bryant,身高是6 ft 6 in(6英尺6英寸),是多高呢?

The foot (pl. feet; abbreviation: ft; symbol: ′, the prime symbol) is a unit of length in the imperialand US customary systems of measurement. Since the International Yard and Pound Agreement of 1959, one foot is defined as 0.3048 meter exactly. Incustomary and imperial units, the foot comprises 12 inches and three feet compose a yard.
1 foot≈30釐米
1 inch≈2.5釐米
1 foot=12 inches
1 yard碼=3 feet
所以科比有多高呢?
