Financial
Calculators 

Loan
Calculator
This
calculator
takes
any
two
of
the
three
variables
(Loan,
Interest
Rate,
and
Number
of
months)
and
gives
the
answer
for
the
remaining
one. 
Lease
Calculator
Leasing
a
car?
Confused
about
the
money
factor
that
car
dealers
always
mention?
We
have
a
mathematical
proof
that
relates
money
factor
to
the
actual
interest
rate. 
APR
Calculator
So
what
is
the
difference
between
APR
and
the
Interest
Rate?
This
calculator
gives
a
full
definition
of
APR
and
helps
you
determine
it
for
a
given
interest
rate
and
points
cost. 
Currency
Calculator
Updated
daily,
this
calculator
gives
the
extrange
rates
of
more
than
60
currencies
and
converts
from
one
to
another.

Aids 

Unit
Conversion
Calculator
Featuring
more
than
800
units
in
our
database
(and
growing),
we
give
the
unit
definition
and
SIdimensions
in
addition
to
converting
from
one
unit
to
other
units
in
the
same
family. 
Fraction
Calculator
Design
engineers,
ever
wonder
what
the
closest
32^{nd}
number
is
for
a
decimal
fraction?
This
calculator
tells
you
where
your
decimal
fraction
stands
on
the
1/8,
1/16,
1/32,
and
1/64
scales. 
Gage
Calculator
There
are
so
many
systems
for
gaging
wires
and
sheets.
This
calculator
allows
you
to
convert
back
and
forth
between
gages
and
the
actual
decimal
numbers
in
different
standards. 
ORing
Calculator
This
calculator
outputs
the
ORing
inner
diameter
and
the
range
of
ORing
crosssection
diameters
that
will
meet
user
prescribed
limits
on
groove
and
bore
diameters
and
ORing
compression. 
Spring
Calculators
Frustrated
by
reading
spring
catalogs
trying
to
figure
out
which
spring
gives
you
the
right
force
or
displacement?
Maybe
one
of
these
8
calculators
can
help
you.
More
calculators
will
be
added
soon! 
Hardness
Approx.
Converter
This
calculator
explains
and
interconverts
comomonly
used
hardness
scales,
including
Brinell,
Knoop,
Mohs,
Rockwell,
Shore,
and
Vickers. 

Mechanical
Formulas 

Beam
Calculators
Featuring
11
calculators
that
output
the
displacement,
rotation,
force,
moment,
and
shear
for
beams
with
different
boundary
conditions
under
various
loadings. 
SDOF
Vibration
This
calculator
returns
the
natural
frquencies,
damping
ratio,
and
the
closedform
solution
for
a
SingleDegreeOfFreedom
massspringdamper
system. 
Reynolds
Number
This
calculator
quickly
gives
you
the
Reynolds
Number
for
a
flow
over
a
plate
or
a
flow
in
a
pipe. 
Venturi
Flowmeter
This
calculator
outputs
the
flowrate
through
a
venturi
constriction
for
a
given
pressure
drop. 
Pipe
Friction
Frustrated
by
using
the
Moody
Chart
to
calculate
pressure
loss
in
pipes?
This
calculator
does
it
for
you
and
tells
you
the
Reynolds
number,
pressure
drop,
and
flow
rate
for
a
constant
crosssection
pipe. 
Radiation
Ever
wonder
how
much
heat
per
second
is
radiated
from
your
(bald)
head
to
the
dark
night
sky
if
you
are
standing
in
an
open
field?
You
can
use
this
calculator
to
figure
that
out!

Stress
Transforms
Remember
Mohr's
Circle?
We
provide
calculators
that
execute
the
math
behind
Mohr's
Circle
for
the
cases
of
Plane
Stress
and
Plane
Strain. 
Principal
Stress
Need
to
find
the
principal
stresses
and
their
directions
for
a
given
input
stress
state?
These
calculators
do
the
math
for
you
for
the
case
of
Plane
Stress
and
Plane
Strain. 
Elastic
Constants
OK,
we
all
remember
that
an
isotropic
material
requires
only
2
elastic
constants
to
describe
its
material
behavior.
But
which
2
constants
to
use?
Youngs
modulus,
Poisson
ratio,
shear
modulus,
or
bulk
modulus?
Don't
sweat
it
anymore

this
calculator
allows
you
to
convert
from
any
2
constants
to
all
others
in
common
use. 
Failure
Criteria
Remember
how
to
apply
von
Mises
and
the
Maximum
Shear
criteria
to
evaluate
failure
risk?
How
about
Maximum
Stress
or
Mohr's
Theory?
We
encourage
you
to
freshen
up
on
the
basics,
but
short
of
that
here
are
2
calculators
for
applying
failure
criteria
to
brittle
and
ductile
materials. 

Pure
Mathematics 

BaseN
Conversions
Converts
integers
expressed
in
one
base
to
all
other
bases,
up
to
base
36. 
Gamma
Function
This
calculator
evaluates
the
Gamma
Function
for
a
given
argument.
We
don't
know
how
useful
this
is,
but
then
again,
it
is
cool! 
Gaussian
Quadratures
GaussLegendre
GaussHermite
GaussLaguerre
These
calculators
output
the
abscissas
and
weights
used
in
Gaussian
quadrature
(a
numerical
integration
technique).
