This calculator allows you to convert from Velocity of sound in sea water (20°C, 10 meter deep) to Cosmic velocity - third and in a reverse direction. To convert from Velocity of sound in sea water (20°C, 10 meter deep) to Cosmic velocity - third, enter the amount of Velocity of sound in sea water (20°C, 10 meter deep) into the first input and to convert from Cosmic velocity - third to Velocity of sound in sea water (20°C, 10 meter deep), enter the amount of Cosmic velocity - third into the second input.
