  1. To express numbers in scientific notation, place the decimal point after the first digit, then add 10x as appropriate (or as E notation)
    700 m = 7.00 x 102 m or 7.00E2 m.
    0.00054 kg = 5.4E-4 kg

  3. I have no idea what a T chart is.
    But you know there are 60 min in an hour and 60 sec in a minute. That's all you need to convert.
