Hectare
The hectare (/ˈhɛktɛər/ or /ˈhɛktɑːr/; symbol ha) is an SI accepted metric system unit of area equal to 100 ares (10,000 m2) and primarily used in the measurement of land. An acre is about 0.4047 hectare and one hectare contains about 2.47 acres.
In 1795, when the metric system was introduced, the "are" was defined as 100 square metres and the hectare ("hecto-" + "are") was thus 100 "ares" or 1⁄100 km2. When the metric system was further rationalised in 1960, resulting in the International System of Units (SI), the are was not included as a recognised unit. The hectare, however, remains as a non-SI unit accepted for use with the SI units, mentioned in Section 4.1 of the SI Brochure as a unit whose use is "expected to continue indefinitely".
History
The metric system of measurement was first given a legal basis in 1795 by the French Revolutionary government. The law of 18 Germinal, Year III (7 April 1795) defined five units of measure:

A Fine Line Between The Middle
by: DiggerAnd when I think of you
I hope we make it through
And when I think I'm strong
You let me know I'm wrong
Everything we ever did
It somehow complicated it
And somehow now we've lost our grip
You've always had me right where you want me
You, you got me wrapped around your finger
You, you got me hoping this gets better
You, you got me wrapped around your finger
You, you got me hoping this gets better
And when I think of me
And how it used to be
I was so different then
I don't know where to begin
Everything we ever did
And somehow now we've lost our grip
You've always had me right where you want me
You, you got me wrapped around your finger
You, you got me hoping this gets better
You, you got me wrapped around your finger
You, you got me hoping this gets better
(You, always. You, always)
You, you got me wrapped around your finger
You, you got me hoping this gets better
You, you got me wrapped around your finger
You, you got me hoping this gets better
You, you got me wrapped around your finger
You, you got me hoping this gets better
You, you got me wrapped around your finger
You, you got me hoping this gets better
You, you got me wrapped around your finger
