簡(jiǎn)單但功能強(qiáng)大的計(jì)算器，單位轉(zhuǎn)換引擎。計(jì)算：發(fā)動(dòng)機(jī)排量，活塞的速度。轉(zhuǎn)換單位功耗和尺寸。 您可以輸入數(shù)據(jù)以公制單位（毫米）或英制單位（英寸）分?jǐn)?shù)英寸或十進(jìn)制。轉(zhuǎn)換毫米英寸太零碎。 *發(fā)動(dòng)機(jī)排量計(jì)算器。 *的壓縮比計(jì)算。 *轉(zhuǎn)換的扭矩和功率計(jì)算或每分鐘轉(zhuǎn)速。 *轉(zhuǎn)換的動(dòng)力單元。 *計(jì)算活塞的平均速度。 *轉(zhuǎn)換長(zhǎng)度單位 *轉(zhuǎn)換和計(jì)算速度的測(cè)量單位不同。 Simple but powerful engine calculator with unit conversion. Calculate: engine displacement, compression ratio, speed of the piston. Convert units of power, torque and size. You can enter data in metric units (mm) or imperial units (inch) in fractional inches or decimal. Convert from millimeters to fractions of inch too. * Engine displacement calculator. * Calculate of the compression ratio. * Converting of torque and calculate power or RPM. * Converting of units of power. * Converts and calculates the speed in different units. * Calculate the average speed of the piston. * Converting units of length.
