A number with many digits may appear as "1e9". This is the computer's exponential representation, where "e" is a power of 10.
1e3 = 103 = 1,000
1e6 = 106 = 1,000,000
1e9 = 109 = 1,000,000,000
1e-3 = 10-3 = 0.001
1e-6 = 10-6 = 0.000001
1e-9 = 10-9 = 0.000000001

## Mass / Weight conversion formula

### Metric system

$1t = 10^3kg = 10^6g$
$1g = 10^{3}mg$

### United States customary units / Imperial units

$1 lb = 0.45359237 kg$
$1 lb = 16 oz = 256 dr = 7000 gr$
$1 s.t. = 20 cwt^{US} = 2000 lb$
$1 l.t. = 20 cwt^{UK} = 80 qtr = 160 st = 2240 lb$

### Japanese units of measurement

$1\text{貫} = 6.25\text{斤} = 100\text{両} = 1000\text{匁} = 3.75 kg$
$1\text{斤} = 16\text{両} = 160\text{匁} = 600 g$
$1\text{両} = 10\text{匁} = 37.5 g$
$1\text{匁} = 3.75 g$
