Famílias de unidades

UnitCloud é um laboratório local de medição para uso diário, engenharia, TI, energia, mobilidade e design.

Comprimento

Inch, foot and mile use fixed factors. Errors usually come from early rounding or from mixing land miles and nautical miles.

Tabela

Unidade base: m
Valores de destino: 11
Unit: nm, µm, mm, cm, m, km

Área

Area scales quadratically. A length factor is not automatically an area factor.

Tabela

Unidade base: m²
Valores de destino: 8
Unit: mm², cm², m², km², ha, acre

Volume

Volume is robust for liquids. For dry ingredients it does not replace weighing because density and packing vary.

Tabela

Unidade base: l
Valores de destino: 11
Unit: ml, cl, dl, l, m³, tsp

Massa

Pound is not always the same local unit. UnitCloud uses international avoirdupois values.

Tabela

Unidade base: g
Valores de destino: 8
Unit: µg, mg, g, kg, t, oz

Temperatura

Temperature uses an offset. Fahrenheit and Kelvin are not pure factor units.

Tabela

Unidade base: °C
Valores de destino: 4
Unit: °C, °F, K, °R

Dados

KB, MB and GB are decimal. KiB, MiB and GiB are binary. This distinction explains many apparent storage gaps.

Tabela

Unidade base: Byte
Valores de destino: 10
Unit: bit, B, KB, MB, GB, TB

Velocidade

Knots are nautical miles per hour. mph and knots are not interchangeable imperial speeds.

Tabela

Unidade base: m/s
Valores de destino: 5
Unit: m/s, km/h, mph, kn, ft/s

Energia

Food calories are kilocalories. Utility bills use kilowatt-hours. Both are energy units, but in different contexts.

Tabela

Unidade base: J
Valores de destino: 8
Unit: J, kJ, Wh, kWh, cal, kcal

Potência

PS and hp are not identical. Vehicle data often uses metric horsepower, while US/UK contexts often use mechanical horsepower.

Tabela

Unidade base: W
Valores de destino: 6
Unit: W, kW, MW, PS, hp, BTU/h

Pressão

bar, psi and atm appear in different fields. Tyre, weather and lab values need context.

Tabela

Unidade base: Pa
Valores de destino: 8
Unit: Pa, kPa, MPa, bar, mbar, psi

Densidade

Density depends on temperature, material state and measurement conditions. Unit conversion does not replace material data.

Tabela

Unidade base: kg/m³
Valores de destino: 4
Unit: kg/m³, g/cm³, g/l, lb/ft³

Tempo

Calendar months and years vary. This family uses fixed seconds for technical durations, not legal deadlines.

Tabela

Unidade base: s
Valores de destino: 7
Unit: ms, s, min, h, d, week

Ângulo

Degrees and radians are often mixed in software, geometry and trigonometry. Formulas usually expect a specific angle unit.

Tabela

Unidade base: rad
Valores de destino: 6
Unit: rad, °, gon, turn, ′, ″

Força

Force and mass are not the same. Kilogram is mass, newton is force.

Tabela

Unidade base: N
Valores de destino: 5
Unit: N, kN, MN, lbf, kgf

Torque

Torque is not power. Newton metre and hp/kW answer different questions.

Tabela

Unidade base: N·m
Valores de destino: 4
Unit: N·m, lb·ft, lb·in, kgf·m

Consumo

mpg and l/100 km move in opposite directions. Higher mpg means lower consumption; higher l/100 km means higher consumption.

Tabela

Unidade base: l/100 km
Valores de destino: 4
Unit: l/100 km, km/l, mpg US, mpg imp

Tipografia

px depends on output context. UnitCloud uses the CSS reference of 96 px per inch.

Tabela

Unidade base: pt
Valores de destino: 6
Unit: pt, pc, in, mm, cm, px

Resolução de imagem

Pixel count and print density are different. Print sizes also need width, height and ppi.

Tabela

Unidade base: px
Valores de destino: 4
Unit: px, kpx, MP, GP

Frequência

rpm and bpm are events per minute. Hz is events per second.

Tabela

Unidade base: Hz
Valores de destino: 6
Unit: Hz, kHz, MHz, GHz, rpm, bpm
