TEAS 7 · Math
The metric ladder, in the 7 steps the TEAS uses
Every metric conversion on the exam is a decimal point moving a known number of places.
No formula and no calculator needed. Count the steps between the two prefixes and move the decimal that many places — right going down the ladder, left going up.
1
kilo– (k)×1000 of the base unit. 1 kg = 1000 g.
2
hecto– (h)×100. Rarely used, but it holds the ladder’s spacing.
3
deka– (da)×10.
4
base unitmetre, gram, litre. The rung everything is counted from.
5
deci– (d)÷10. 1 dL = 0.1 L.
6
centi– (c)÷100. 1 cm = 0.01 m, so 100 cm = 1 m.
7
milli– (m)÷1000. 1 mL = 0.001 L, and 1000 mL = 1 L.
