# FREQ. Help

I have a Shortwave Radio that tunes in on Kilo Herts.

So my display says
1015 kHz

Now if I want to write this out I would write
101,500,000 Hz

Now if I am on a Radio that tunes in on MHz and the display says
101.5 MHz

Now if I want to write this out I would write
101,500,000 Hz

Now this is what I do not understand they are both the same FREQ but I do not get how you tune them in on MHz and kHz?

I know MHz meens it will tune in at 1,000,000 Hz and if you tune in at Kilo Hz it will be 1,000 Hz

I hope I am asking in the right way if not please tell me?

I'd write 1015 kHz as 1,015,000 Hz

You're losing track of decimal places, the 'k' in kHz moves the decimal point 3 digits to the right of a number to go to just Hz. Therefore 1015. kHz = 1015000. Hz = 1,015,000 Hz.

Likewise, converting to MHz from kHz is as simple as moving the decimal point 3 digits to the left, so 1015. kHz = 1.015 MHz.

Ok so if I see a readout of
1015. kHz
I would say
1015,000. Hz

And if I see a readout of
1.015 MHz
I would say
1,015,000,000 Hz

Do I have it?

Not exactly... MHz is 10^6, so 1.015 MHz is 1,015,000 Hz. You might be just better off quoting all the frequencies as MHz or kHz though.
