Weighted difference formula and comparison chart.
( NIST - suggested ) / suggested * 100
example for c
1 the first radiation constant.
NIST = 3.74177107 suggested = 3.75
( 3.74177107 - 3.75 ) / 3.75 * 100
-0.00822893 / 3.75 = -0.002194381 times 100 = -0.21944381
is the weighted value for c
1 the first radiation constant.
