In which unit is mass entered?
Answer: Mass must be given in consistent mass units (W/g).
...
Force,
...
length,
...
and
...
temperature
...
are
...
primary
...
units.
...
Mass
...
is
...
then
...
derived
...
from
...
these
...
units
...
secondarily.
...
Accordingly,
...
notable
...
points
...
include
...
the
...
following:
...
- Ton
...
- represents
...
- ton-force
...
- (tonf)
...
- when
...
- the
...
- Ton,
...
- m,
...
- C
...
- unit
...
- set
...
- is
...
- chosen.
...
- A mass of 1.0
...
- tonm,
...
- also
...
- known
...
- as
...
- a
...
- tonne
...
- or
...
- metric
...
- ton,
...
- is
...
- given
...
- as
...
- 1000
...
- kg.
...
- In
...
- a
...
- standard
...
- gravity
...
- field,
...
- the
...
- weight
...
- of
...
- 1.0
...
- tonm
...
- produces
...
- 1.0
...
- tonf,
...
- or
...
- a
...
- ton-force,
...
- given
...
- as
...
- 9810
...
- Newtons
...
- (N).
...
- Because mass must be entered in consistent units (W/g),
...
- and
...
- not
...
- as
...
- a
...
- force,
...
- 1.0
...
- tonf
...
- would
...
- be
...
- entered
...
- as
...
- W/g
...
- =
...
- 1
...
- tonf
...
- /
...
- (9.81
...
- m/s
...
- 2)
...
- =
...
- 0.102

- tonf
