Surface tension
Dynes per centimeter to millinewtons per meter
dyn/cm → mN/m
72.8 dyn/cm = 72.8 mN/m
Millinewtons per meter to dynes per centimeter
mN/m → dyn/cm
30 mN/m = 30 dyn/cm
Newtons per meter to dynes per centimeter
N/m → dyn/cm
0.0728 N/m = 72.8 dyn/cm
Dynes per centimeter to pounds-force per inch
dyn/cm → lbf/in
72.8 dyn/cm = 0.000416 lbf/in
