Introduction

HAMILTON KHAKI AVIATION CONVERTER / 3
Multiplications
A
Multiplication
For multiplication, turn the bezel Ato align the
number chosen as the common multiplier, in
this case 15 (orange arrow), with index 10 on
the ange (black arrow).
The result (green arrow) appears opposite the
multiplied number (red arrow).
Below are three examples of calculations per-
formed using 15 as the common multiplier.
14 x 15 = 210
16 x 15 = 240
30 x 15 = 450
Note: Depending on the numbers used in the
calculations, the results can be read in simpli-
ed terms.
For example, if the result displayed is 21, this
can also mean:
2.1 for a multiplication of 1.4 x 1.5
21 for a multiplication of 1.4 x 15 or 14 x 1.5
210 for a multiplication of 14 x 15
2,100 for a multiplication of 140 x 15 or 14 x 150
21,000 for a multiplication of 140 x 150 or
14 x 1,500

Division
A
Division
For division, turn the bezel Ato align the number to divide, in this case 40 (orange arrow), with
the divisor number on the ange, in this case 8(black arrow).
The result (green arrow) appears opposite index 10 on the ange (red arrow) and must logically
be read as 5.
Reading examples:
40/8= 5
40/0.8 = 50
400/8= 50
400/0.8 = 500
4,000/80 = 50

KM / NAUT
A
KM / STAT
A
Converting kilometers to nautical miles or statute miles
To convert kilometers (KM) to nautical miles (NAUT) or statute miles (STAT) or vice-versa, turn the
bezel Ain order to align the “NAUT” or “STAT” index (orange arrow) with the “KM” index on the
ange (black arrow).
The result (green arrow) can immediately be seen opposite any number indicated on the ange
(red arrow).
Examples KM - NAUT:
50 KM = 27 NAUT or 5KM = 2.7 NAUT
74 KM = 40 NAUT or 7.4 KM = 4NAUT
Examples KM - STAT:
45 KM = 28 STAT or 4.5 KM = 2.8 STAT
70 KM = 43.5 STAT or 7KM = 4.35 STAT
« KM - NAUT » « KM - STAT »

CHF / €
A
Converting currencies
Example: You would like to convert Swiss Francs into Euros. The exchange rate is CHF 1.20 for EUR 1.
To do this, turn the bezel Ato align the exchange rate, in this case number 12 for CHF 1.20 (orange
arrow), with index 10 on the ange (black arrow).
The result (green arrow) appears opposite any number indicated on the bezel (red arrow).
Three examples:
CHF 3= EUR 2.5
or
CHF 30 = EUR 25
or
CHF 300 = EUR 250
CHF 7.2 = EUR 6
or
CHF 72 = EUR 60
or
CHF 720 = EUR 600
CHF 9= EUR 7.5
or
CHF 90 = EUR 75
or
CHF 900 = EUR 750

Ground speed
MPH / km/h
A
Ground speed
Example: A pilot travels 112 miles in 28 minutes. What is his ground speed?
To calculate his average ground speed, turn the bezel Ato align 28 minutes (orange arrow) with
112 miles on the ange (black arrow).
Result: 240 MPH (green arrow) appears opposite “MPH” indicated on the bezel (red arrow).
You can also instantly convert the speed to miles per minute by reading the number (green arrow)
opposite index 10 on the bezel (red arrow).
In this case: 4miles/min.
Note: The values shown in miles can be replaced with kilometers (km) or knots.

HAMILTON KHAKI AVIATION CONVERTER / 8
Distance covered
A
Distance traveled
Example: A pilot wishes to calculate the distance he will travel in 25 minutes at a speed of 156 MPH.
To calculate the distance traveled, turn the bezel Ato align the “MPH” index (orange arrow) with
the speed “15.6” on the ange (black arrow).
The result 65 miles (green arrow) appears opposite 25 minutes indicated on the bezel (red arrow).
Note: The values shown in miles can be replaced with kilometers (km).

HAMILTON KHAKI AVIATION CONVERTER / 9
Lt / 100 km
A
Fuel consumption per 100 km
Example: 55 liters of fuel were required to travel 800 km.
To calculate a vehicle’s fuel consumption in liters/100 km, turn the bezel Ato align the 55 liters
consumed (orange arrow) with the 800 km traveled on the ange (black arrow).
Result: 6.9 liters for 100 km (green arrow) appears opposite index 10 on the ange (red arrow).

HAMILTON KHAKI AVIATION CONVERTER / 10
Short time mesurement
A
Calculating short time spans
Example: A pilot is on approach to the airport at a ground speed of 190 MPH. Given that the
VOR beacon is located 1.5 miles ahead of the start of the runway, he wishes to know how many
seconds there are between the beacon and the runway.
To calculate this short time span, turn the bezel Ato align the speed 190 MPH “19” (orange arrow)
with index “36”* on the ange (black arrow).
Result: 28.5 seconds (green arrow) appears opposite the distance 1.5 miles “15” indicated on
the bezel (red arrow).
Note: The values shown in miles can be replaced with kilometers (km).
* Index 36 on the flange (black arrow) corresponds to the factor for converting hours to seconds.

LITERS / GAL
A
KG / LBS.
Meters / Feets
Converting volumes, weights and lengths
Depending on the desired conversion, turn the bezel Ato align the “GAL.”, “LBS.” or “Ft.” index
(orange arrow) with the “LITERS”, “KG” or “METERS” index on the ange (black arrow).
The result (green arrow) can immediately be seen opposite any number indicated on the ange
(red arrow).
“LITERS - GAL.”
Liters - US gallons
“KG - LBS.”
Kilograms - US pounds
“METERS - Ft.”
Meters - Feet
Example:
50 LITERS = 13.2 GAL.
or
5LITERS = 1.32 GAL.
Example:
7.9 KG = 17.4 LBS.
or
79 KG = 174 LBS.
Example:
14 METERS = 46 Ft.
or
140 METERS = 460 Ft.
