You can put this solution on YOUR website!
70 m * (100cm)/(1m) * (1 in)/(2.54 cm) = 2755.9 in
\n" ); document.write( ".
\n" ); document.write( "Rough check, 1 m = 39.36 in approx , 70*39.36 = 2755.2 in ok
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "Note: dimensions only,,,(m) * (cm)/(m) * (in)/ (cm) shows cancellation of dim's
\n" ); document.write( ".
\n" ); document.write( "hence,,,the name,,,,,,dimensionless analysis,,,,
