Use this if you want to have just 2 significant digits:

String str = "6.151536E-8";  
BigDecimal bd = new BigDecimal(str);
bd = bd.round(new MathContext(2, RoundingMode.HALF_UP));
System.out.println(bd.toPlainString());

This prints: 0.000000062

If you want to round down to 0.000000061 then use RoundingMode.DOWN
