simple question regarding power

is -5dBm (power) is lessthan or greater than the -10dBm power ??

i am just confused......

-5dBm > -10dBm

There is no negative power.

is -3db < -10db ??? then it should be -3dbm < -10 dbm????

dBm = log10 (mW)*10
mW =10^(dBm/10)

-10dBm is 0.1mW
-5dBm is 0.3162mW
Now you decide which is less

40 dBm 10.00 watts
36 dBm 4.00 watts { Maximum ERP allowed by FCC in U.S.
30 dBm 1.00 watts
27 dBm 500 milliwatts
26 dBm 400 milliwatts
25 dBm 320 milliwatts
24 dBm 250 milliwatts
23 dBm 200 milliwatts { Typical output from WLAN devices at 915MHz
22 dBm 160 milliwatts
21 dBm 130 milliwatts
20 dBm 100 milliwatts { Maximum ERP allowed by E.T.S.I. In Europe
15 dBm 32 milliwatts
10 dBm 10 milliwatts
5 dBm 3.2 milliwatts
4 dBm 2.5 milliwatts
3 dBm 2.0 milliwatts
2 dBm 1.6 milliwatts
1 dBm 1.3 milliwatts
0 dBm 1.0 milliwatts
1- dBm 0.79 milliwatts
5- dBm 0.32 milliwatts
10- dBm 0.1 milliwatts
20- dBm 0.01 milliwatts
30- dBm 0.001 milliwatts
40- dBm 0.0001 milliwatts
50- dBm 0.00001 milliwatts
60- dBm 0.000001 milliwatts
70- dBm 0.0000001 milliwatts
80- dBm 0.00000001 milliwatts {Receive threshold for most WLAN devices

Wrong !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

What made you say so with respect to power conversion

Expecting an reply from you

so there is no negative power....so -5 dBm > -10 dBm.

yes............... even basic of maths says -5 is bigger than -10. so same convention is true in all cases
