The short version
The Standard Drink / Units Calculator is free, needs no account, processes everything in your browser, works on mobile, and keeps your data on your device. Below: the question bank — from basics to edge cases — each answered in plain language.
Deeper background on how this works
Total Daily Energy Expenditure = BMR (what you burn existing) × activity multiplier. BMR via Mifflin-St Jeor is the current best common formula (weight, height, age, sex). TDEE is an ESTIMATE with ±10–20% individual variance — calculators give a starting number; 2 weeks of weight data recalibrates it better than any formula.
Fat loss math that isn't controversial: ~500 kcal/day deficit ≈ 0.5 kg/week (7,700 kcal ≈ 1 kg fat). Surplus for muscle gain: +200–300/day (slower than beginners hope). Diets succeed by controlling intake through different mechanisms (keto restricts carbs, fasting restricts windows, volume eating restricts density) — adherence, not mechanism, predicts results.
Can / is / does questions (6)
Is the standard drink / units calculator really free?
Yes — no sign-up, no limits, no watermarks. Toolfyra runs client-side, so there is no server cost to pass on to you.
Does the standard drink / units calculator work offline?
After the first load, most browsers cache the page and it keeps working without a connection — results compute on your device.
Is my data uploaded anywhere?
No. Processing happens locally in your browser via standard web APIs — nothing is transmitted to any server. Verify it in the Network tab if you like.
What's a normal resting heart rate?
60–100 bpm is the standard adult range; 40–60 common in trained athletes. Trends matter more than single readings — rising resting HR over days can signal overtraining or illness. Fitness trackers show your baseline; compare against your own trend.
What's my ideal weight?
BMI-based ranges (18.5–24.9 for your height) are the conventional answer; body-composition goals (body-fat %, waist) are the more useful personal target. Ideal-weight calculators show the historical formulas (Devine, Hamwi — designed for drug dosing originally); use them as context, not commandments.
Is intermittent fasting right for me?
It's an adherence tool, not a metabolism trick — fasting-window planners schedule 16:8 or similar; total calories still decide the outcome. Works well for people who prefer not eating breakfast; irrelevant for those who don't. Medical conditions (diabetes, pregnancy, history of disordered eating) need professional guidance first.
What, which & when questions (3)
Which browsers are supported?
All modern browsers: Chrome, Edge, Firefox, Safari (desktop and iOS/Android). The tool adapts to your screen and language automatically.
What are macros and how do I set them?
Protein/carb/fat gram targets inside your calorie budget. Evidence-based: protein 1.6–2.2 g/kg (higher in a deficit), fat ≥20% of calories, carbs fill the rest. Macro calculators do the split from your goal — then a food scale makes the targets real.
When are my most fertile days?
Ovulation ≈ 14 days before next period (cycle length minus 14); fertile window spans ~5 days before through 1 day after (sperm survive days, egg hours). Ovulation calculators estimate from cycle averages — irregular cycles make estimates unreliable (OPK strips and cervical mucus tracking beat calendar math there).
How-to questions (11)
How do one-rep max calculators work?
Formulas (Epley: weight × (1 + reps/30)) estimate 1RM from a submaximal set — 5 reps at 100 kg ≈ 113 kg 1RM. Use the estimate for programming percentages (%1RM training zones) rather than actually maxing — testing true 1RM is a risk with little programming benefit. Accuracy degrades beyond ~8 reps.
How do I gain muscle without getting fat?
Modest surplus (+200–300 kcal), protein 1.6–2.2 g/kg, progressive overload in training, patience (0.25–0.5 kg/month gain rate for intermediates). Macro and TDEE calculators set the numbers; the scale trend over months tells you if the surplus is too big (fat gain) or too small (no gain).
How is BMI calculated and what's a healthy range?
Weight (kg) ÷ height² (m). Healthy range: 18.5–24.9, with caveats — muscular people read high, and some Asian-population guidelines use lower thresholds. BMI is a screening starting point; body-fat % and waist measurements add the individual picture a BMI calculator can't.
How many calories should I eat to lose weight?
Estimate TDEE (BMR × activity), subtract 300–500 for sustainable loss (~0.5 kg/week). Below BMR aggressively and adherence + muscle loss fight you. TDEE calculators give the starting number; two weeks of real-world weight data calibrates it better than any formula.
How much protein do I need daily?
Sedentary: 0.8 g/kg (RDA minimum). Active/muscle goals: 1.6–2.2 g/kg. Over 100 kg or cutting hard: lean-mass-based targets. Protein calculators translate body weight and goal into grams — spread across 3–4 meals for utilization.
How do I calculate my max heart rate and training zones?
Estimate: 220 − age (or Tanaka 208 − 0.7×age, slightly better). Zones split the range: Z2 60–70% (easy, conversational — the zone most people skip), Z4 80–90% (threshold, comfortably hard). Zone calculators output all five; use them to keep easy days easy and hard days hard.
How many steps a day do I actually need?
7,000–8,000 shows most of the mortality benefit in modern cohort studies (the 10,000 figure came from a 1965 Japanese pedometer campaign). Steps-to-calories calculators estimate burn (modest: ~30–50 kcal per 1,000 steps depending on weight) — the health value is movement, not the burn.
How much water should I drink daily?
Rough baseline: 30–35 ml/kg body weight (2–2.5 L for most adults), more with heat/exercise. Urine color is the practical check (pale yellow = fine). Water-intake calculators personalize for weight and activity; the '8 glasses' rule is a rough approximation of the same target.
How is due date calculated?
LMP + 280 days (Naegele's rule) — counting from the last period, not conception. Adjust for cycle length if yours differs from 28 days. Only ~4% deliver on the date; 37–42 weeks is full-term range. Due-date calculators also show current week and trimester.
How do I calculate body fat at home?
Methods ranked by accessibility/accuracy: tape-measure Navy method (±3–4%), calipers (skill-dependent), bioimpedance scales (±3–5%, hydration-sensitive), DEXA scan (gold standard). Body-fat calculators implement the Navy tape method — consistent measurement technique matters more than method choice for tracking trends.
How accurate are calorie burn estimates?
Formulas and machines: ±20–30% typical overestimation. They don't know your metabolism, efficiency or heart rate. Use estimates as rough relative guides (this workout burned more than that one), calibrate against weight trends over weeks — the trend is the truth.
