Který z následujících převodů není správně?
Správná odpověď je: A
Pro jednotku síly newton (N) platí následující převodní vztahy:
10−9 GN = 10−6 MN = 10−3 kN = 1 N = 103 mN = 106 μN = 109 nN = 1012 pN.
Při výběru libovolných dvou násobných jednotek z této řady lze posoudit jejich shodnost nebo řádový rozdíl převedením na watty a srovnáním jejich exponentů.
A: 1 kN = 103 N; 10−9 μN = 10−9 · 10−6 N = 10−15 N.
B: 10 μN = 101 · 10−6 N = 10−5 N; 107 pN = 107 · 10−12 N = 10−5 N.
C: 1 MN = 106 N; 109 mN = 109 · 10−3 N = 106 N.
D: 100 GN = 102 · 109 N = 1011 N; 1020 nN = 1020 · 10−9 N = 1011 N
