#1 kgwt# is the weight of a mass of #1kg# and is equal to #9.81 N# according to #w=mg#, where #w# is weight, #m# is mass and #g# is acceleration due to gravity.
The spring balance has graduations in #0.5kgwt# which is equal to #(9.81*0.5) = 4.91N#
The block starts moving when the pointer is at the #25th# division, which is equal to #(4.91*25) = 122.6N# correct to 1 decimal place.
