1,011

[Math.]  (Sequence of numbers 10…0112 = 10…022…121).

10112 = 1,022,121 and 1022–12+1 = 1011.

 

1012...

 

1,013

[Math.]   A prime number.

 

1013.25

[Measure]  The standard atmospheric pressure at sea level is 1 atm (atmosphere) = 1,013.25 millibars = 29.921 inches of mercury (inHg).

Units for pressure measures:

 1 atm (atmosphere) = 1013.25 millibars = 101,325 N/m2 (pascals) = 1033.227 g/cm2 = 10,332.27 kg/m2 = 760 mmHg (torrs) = 29.921 inHg = 14.696 lb/inch2 (psi)

& 1 bar = 105 N/m2 (pascals) = 106 dynes/cm2 (cgs bars).

1,014

[Math.]  (Sequence of numbers 10…0142 = 10…028…196).

10142 = 1,028,196 = (1028+1–9–6)2.

 

1,015

[Math.]   A pyramidal number (sum of all squares of integers from 1 to 14):

1015 = 12+22+…+132+142.

 

1,016.0469

[Measure]  1 long ton (or gross ton) = 20 long (gross) hundredweights = 2,240 lb (pounds) = 1016.0469 kg (kilograms).

1 short ton = 20 hundredweights = 2,000 lb (pounds) = 907.1847 kg (kilograms).

 

1017...

 

1,018

[Math.]  10183 = 1,054,977,832 and 1054–(9+7+7+8+3+2) = 1018.

 

1,019

[Math.]  A prime number.
