The weight of the journey of mathematical practice
One kilogram is 500g (10 the weight of an egg), one kilogram is 1 000g (the weight of 20 eggs),1lb = 0.454kg = 454g (similar to one kilogram, foreign units), and one ton is1000kg.

Because every country and region is different, it is difficult to ask for the heaviest unit and the lightest unit. However, under the international system of units, the largest unit is tons, and the smallest unit is milligrams. When 1000 milligrams is1g.

One inch is 3.33333 centimeters, the length of an adult's thumb is about 2 inches, one foot is 0.33333 meters, one meter is three feet, a person's height is about 5 feet -6 feet, one kilometer is one kilometer, a standard playground is 400 meters, and one kilometer has two and a half laps.

Please refer to the following

1 long ton) = 1.0 16+06 ton (t) 1 kg) =2.205 lbs.

1 lb) = 0.454kg) [constant] 1 oz) =28.350 (g)

1 short ton =0.907 ton =2000 lbs.

1 ton (t)= 1000 kg)=2205 lb =1.102 short ton (sh.ton)=0.984 long ton.

1 km (km)=0.62 1 mile (m)=3.28 1 foot (ft)= 1.094 yards (yd).

1 cm) =0.394 inch (inch) 1 inch (inch) =2.54 cm.

1 nautical mile = 1 .852km1fathom (FM) =1.829m.

1 yard =3 feet 1 rod (radian) = 16.5 feet

1 mile = 1.609 km 1 foot = 12 inch

1 mile) = 5280ft 1 nautical mile = 1. 15 16 mile.
